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.

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 Continue reading

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 Continue reading
