The Cincinnati Chapter of the IEEE is proud to offer a presentation of the state of the art in Cognitive Radio Technology by two leading experts in the field, Dr. James Neel, President and co-founder of Cognitive Radio Technologies (CRT), and David Maldonado, Business Development manager at L-3 Nova Engineering. This emerging technology is having a profound effect on the way radios and frequency spectrum will be used in the future. Both gentleman are graduates of Virginia Tech, a pioneering institution in cognitive radio technologies.

From Wikipedia: “Cognitive radio is a paradigm for wireless communication in which either a network or a wireless node changes its transmission or reception parameters to communicate efficiently avoiding interference with licensed or unlicensed users. This alteration of parameters is based on the active monitoring of several factors in the external and internal radio environment, such as radio frequency spectrum, user  behavior and network state.
The idea of cognitive radio was first presented officially by Joseph Mitola III in a seminar at KTH, The Royal Institute of Technology, in 1998, published later in an article by Mitola and Gerald Q. Maguire, Jr in 1999.[1] It was a novel approach in wireless communications that Mitola later described as:
The point in which wireless personal digital assistants (PDAs) and the related networks are sufficiently computationally intelligent about radio resources and related computer-to-computer communications to detect user communications needs as a function of use context, and to provide radio resources and wireless services most appropriate to those needs.[2]
It was thought of as an ideal goal towards which a software-defined radio platform should evolve: a fully reconfigurable wireless black-box that automatically changes its communication variables in response to network and user demands.”

Dr. James Neel is the President of Cognitive Radio Technologies, which he founded in 2007 with Dr. Jeff Reed to commercialize cognitive radio research from Virginia Tech. The leading small business for incorporating artificial intelligence into wireless networks with three SBIRs on cognitive spectrum management and contracts on topics ranging from applying behavioral learning to detecting the intention of wireless networks to rapidly deployable networks for disaster responses. Dr Neel is the Chair of the Cognitive Radio Work Group in the Wireless Innovation Forum (formerly the SDR Forum), and has received three paper awards for the design of cognitive radio networks.

Mr. David Maldonado is currently the Manager of the Advanced Programs and New Technologies Development Group at L-3 Nova Engineering.  In addition, Mr. Maldonado is part of the Business Development group.  In his combined role, Mr. Maldonado is responsible for identifying new technologies and emerging markets of business development. He is also part of the company’s Internal Research and Development (IRAD) selection committee.  It is in this capacity that Mr. Maldonado has participated in the system engineering of various next generation SDR-based communications systems and supported integration, test and evaluation of Cognitive Radio algorithms into the company’s product offerings. Mr. Maldonado has also contributed to the creation of a tightly integrated development process between the modeling, simulation and hardware development teams to ensure a successful and more effective transition of innovations to deployable systems. Much of this work has been integral to L-3 Nova Engineering’s maturation, rapid integration and transition of technologies developed in conjunction with Small Business and University partners directly impacting DoD developments such as the JTRS WNW waveform program.

Mr. Maldonado obtained his MS from Virginia Tech (VT) where he is currently working on his PhD degree. As part of his work, Mr. Maldonado was one of the pioneers of the Center for Wireless Telecommunications (CWT) Cognitive Engine (CE) at VT. He has been part of Cognitive Radio developments since its inception and an active participant of the Wireless Innovation Forum (formerly the SDR Forum) Cognitive Radio Working Group where he held Vice-Chair and Chair positions.

Prior to Joining L-3 Nova Engineering, Mr. Maldonado held a District Sales Manager position at Anritsu Company as part of their wireless Test and Measurement (T&M) group where he served as a liaison between Sales, Marketing and Engineering groups. Mr. Maldonado’s career in advanced wireless development started in the commercial arena as an RF engineer of Ericsson’s Mobile Handset R&D group.

Scanning the Past: A History of Electrical Engineering from the Past
Submitted by Marc Bell, Editor

Copyright 1997 IEEE. Reprinted with permission from the IEEE publication, “Scanning the Past” which covers a reprint of an article appearing in the Proceedings of the IEEE Vol. 85, No. 2, February 1997.

Rudolf Kompfner and the Traveling-Wave TYibe    

     Fifty years ago this month, the PROCEEDINGS OF  THE RADIO ENGINEERS (IRE) included a paper by Rudolf Kompfner (see Fig. 1) img014.jpgon the traveling-wave tube as a microwave amplifier. At the time he was affiliated with the Clarendon Laboratory of Oxford University in England. He received the IEEE Medal of Honor in 1973 as recognition of having made “a major contribution to worldwide communication through the conception of the traveling-wave tube embodying a new principle of amplification.” He also made significant contributions to the development of communication using earth satellites.
     Kompfner was born in Vienna, Austria, in 1909. He graduated with a degree in architecture from the Technische Hochschule in Vienna in 1933. In 1934, he moved to England, where he worked as an architect and developed a vocational interest in radio and electronic tubes. He took advantage of the facilities available at the Patent Office Library and began to write for radio journals in his spare time. After the outbreak of World War II in 1939, he was interned as an alien on the Isle of Man but was released in 1941 to join the staff of an advanced electronics laboratory at the University of Birmingham. The laboratory was directed by Mark L. Oliphant and was the site of the demonstration of the resonant cavity magnetron as a high-power microwave generator by Henry A. H. Boot and John T. Randall early in 1940.
     Assigned to work on development of a klystron amplifier, Kompfner determined that the coupling between the radio frequency field in resonator gaps and img015.jpgthe electron beam was too weak to give suitable results. In the fall of 1942 he came up with the idea of creating an interaction between a traveling electromagnetic wave and an electron beam. In a notebook entry dated November 12, 1942, he mentioned “a completely untuned amplifier” and his sketch showed a helix between the input signal and output (see Fig. 2). For a time he called it a “helical coaxial-line amplifier.” Several colleagues left the laboratory to take up research related to atomic bombs, but Kompfner continued to work on the traveling wave concept as “spare-time amusement” from his principal assignment of klystrons. He obtained amplifi¬cation (see Fig. 3) for the first time with an experimental traveling-wave tube (Fig. 4) on November 1, 1943. In 1944, he was transferred to the Clarendon Laboratory at Oxford where he and Joseph Hatton, a research assistant, continued theoretical and experimental research on the new device. They shared their findings with John R. Pierce of the Bell Telephone Laboratories who visited Oxford in 1944 and who soon produced a more elegant theory of traveling-wave tubes.
     Information about the research on traveling-wave tubes remained secret until June 1946 when Joseph Hatton pre¬sented a paper about it at an electron tube conference at Yale University. More complete information was provided by Kompfner’s paper in the February 1947 issue of the PROCEEDINGS and two papers by Pierce (one with L. M. Field as coauthor) in the same issue. Pierce’s book Traveling-Wave Tubes was published in 1950. Kompfner received a doctorate in img016.jpgphysics from Oxford in 1951 and joined Pierce’s group at the Bell Laboratories the same year. Continuing work he had started in England, Kompfner developed a backward-wave oscillator and amplifier which could be tuned electronically. He disclosed this discovery at a tube conference in Ottawa, Canada, in June 1952.
     Kompfner began theoretical work on earth satellite com-munication by 1958 and published a joint paper with Pierce in the March 1959 PROCEEDINGS OF THE IRE, entitled ‘Transoceanic Communication by Means of Satellites.” They considered both passive and active satellites and concluded that they had “a great deal of confidence in the overall feasibility of satellite communications.” Their work contributed to such early projects as the passive satellite Echo launched in 1960 and the active repeater satellite Telstar in 1962.
    img017.jpg Kompfner retired from Bell Laboratories and subse¬quently taught at Stanford University and at Oxford. He was elected to both the National Academy of Sciences and the National Academy of Engineering. His book The Invention of the Traveling-Wave Tube was published by San Francisco Press in 1964. His colleague John Pierce wrote that the book “can tell you something of the strange and wonderful ways in which important inventions and discoveries are actually made.”
     Kompfner died in December 1977 at age 68.

IEEE/IEEE-USA’s New Face of Engineering Honored for Technological Innovations Benefiting Women and Children

WASHINGTON (1 March 2011) — Sampathkumar Veeraraghavan was recognized as the IEEE/IEEE-USA’s 2011 New Face of Engineering during National Engineer Week for developing technological solutions that improve the lives of disabled and impoverished women and children in India.Veeraraghavan was one of 14 engineers recognized for this international honor and featured in a full-page ad in USA Today on 21 February:   I’m humbled by this honor and would like to dedicate it to the disabled children that benefit from our programs,” Veeraraghavan said. “The recognition has motivated me to strongly pursue my passion toward designing engineering solutions to solve global humanitarian issues. In coming years, I will continue working to develop more technological solutions, and will strive hard to bring many more positives changes to the living conditions of people with disabilities.” Engineers Week (EWeek) was celebrated in the United States 20-26 February.Veeraraghavan, 27, is a component design engineer with the Intel Corp. and lives in Hudson, Mass. He earned his master’s degree in electrical engineering from Tufts University in Medford, Mass., in May 2010.After graduating from India’s Anna University with a bachelor’s degree in computer science and engineering in 2005, Veeraraghavan visited a local school for developmentally disabled children in Chennai, India, where he saw children with autism, cerebral palsy, Down syndrome and other disorders. Their needs varied so much that proper therapy was impossible.So he and a group of medical professionals developed the Automated Screening System for Developmental Disorders, a 30-minute screening procedure that assists in the early detection of autism in children as young as 18 months.

According to a 2008 story in The Institute, the procedure “evaluates the child’s fine and gross motor, social, and language skills through 48 questions aimed at the primary caretaker, and includes artificial-intelligence gaming systems for the child. The screening system assigns each question or task a different numerical value that, when computed, add up to a score that could suggest symptoms of autism.”

The entire article is available at

Veeraraghavan recently created India’s first online database to collect and analyze information on the physically and mentally disabled. The Information System on Human and Health Services is helping to close the sizable gap in medical resources available to women and children in urban vs. rural areas. More than two million people in the Indian state of Tamil Nadu have been impacted by the system. Veeraraghavan has received numerous awards from IEEE and other organizations for his humanitarian work.The New Faces of Engineering program is sponsored by the National Engineers Week Foundation, a coalition of engineering societies, major corporations and government agencies. The program highlights the vitality, diversity and rich contributions of engineers under 30. They are honored annually during EWeek. IEEE-USA has participated in the program since its inception in 2003.A New Faces of Engineering, College Edition, is being started to promote the accomplishments of fourth- and fifth-year engineering students. It will highlight their academic success and student contributions to the industry and sponsoring society.

Discover Engineering Family Day Shatters Attendance Record; IEEE-USA Recognizes New Face of Engineering, Presents Awards at Future City Competition

WASHINGTON (25 February 2011) — Discover Engineering Family Day drew a National Building Museum one-day record 13,994 visitors on Saturday 19 February to kick off National Engineers Week activities in the nation’s capital. IEEE-USA, which played a leadership role in the launch of the first Family Day in 1993, is one of the event’s major sponsors.Family Day introduces children to basic engineering concepts with hands-on and thought-provoking activities. At IEEE-USA’s exhibit, children learned about what type of materials conduct electricity and how basic electrical circuits and light bulbs operate. See Washington FOX 5 coverage at Tuesday, IEEE-USA President Ron Jensen presented awards to two teams at the Future City Competition National Finals: the third-place award to Davidson (N.C.) IB Middle School; and the Best Communications System Award to the Alexander Dawson School of Las Vegas. The third-place team will receive a $2,000 scholarship from IEEE-USA for the school’s science and technology program. IEEE-USA EWeek liaison Murty Polavarapu and fellow Virginia IEEE member Kiki Ikossi judged the communications award. Each of those students will also receive a $100 U.S. Savings Bond.The Future City Competition (, conceived in IEEE-USA offices in 1993, is designed to promote technological literacy and engineering to middle school students. Under the guidance of an engineer/mentor and teacher, children create their own vision of a future city, working first on computer and then constructing three-dimensional scale models. The students also have to write an essay about a predetermined challenge the city might face.More than 1,100 schools and 33,000 students from across the United States competed during the 2010-11 season. Thirty-five regional champions earned a trip to Washington for the National Finals.  Sampathkumar Veeraraghavan was recognized as the IEEE/IEEE-USA New Face of Engineering. An electrical engineer and recent graduate of Tufts University, Veeraraghavan develops technological solutions to global humanitarian issues for disabled and impoverished women and children. He was one of 14 engineers featured in a full-page ad in USA Today on Monday: New Faces of Engineering recognition program is sponsored by the National Engineers Week Foundation, a coalition of engineering societies, major corporations and government agencies.
