Since the seminal work of Foschini, Gans and Teletar [ref] the research community has generated well over 10,000 papers and articles dealing with various aspects and benefits of MIMO for wireless data communications. These papers have for the most part dealt with the application of MIMO in civilian and commercial systems. To date, there has been little work that focuses on MIMO techniques that specifically address the needs of the military customer. Of particular interest in military communications is: (a) adaptability to changing mission requirements; (b) MIMO communications for UAV and other highly mobile platforms; (c) the use of multi-antenna techniques for covert communications; and (d) jammer/interference immune communications. In this paper we provide results of the use of MIMO communications to address the four points mentioned above. In particular our results show the ability to operate at speeds of up to 500 mph, a 17 dB reduction in the required TX power for covert, LPD communications, and a unique interference/jammer mitigation technique based on MIMO eigen-nulling. Moreover, we report on the development of a highly versatile MIMO SDR platform that will be used to validate the simulation results under real-world operating conditions.

Babak Daneshrad is an Associate Professor with the Electrical Engineering Dept. at the University of California, Los Angeles (UCLA). His interests include experimental wireless communication systems and VLSI ASICs for wireless data communications. He obtained the BEng. and MEng. degrees with emphasis in Communications from McGill University, in 1986 and 1988 respectively, and the Ph.D. degree from UCLA in 1993 with emphasis in Integrated Circuits and Systems. His current research interests are cross disciplinary in nature and deal with addressing practical issues associated with the realization of advanced wireless systems. The work is focused on experimental MIMO wireless systems, and in particular the practical challenges for delivery of Gbps links in the unlicensed bands. He is the recipient of the 2005 Okawa Foundation award, the best paper award at PADS 2004, and was awarded first prize in the DAC 2003 design contest. He is also the beneficiary of the Endowment for “UCLA-Industry Partnership for Wireless Communications and Integrated Systems”. In Jan. 2001 he co-founded Innovics Wireless a company focused on developing mobile terminal antenna diversity solutions for the cellular industry. From 1993 to 1996 he was a member of technical staff with the Wireless Communications Systems Research Dept. of AT&T Bell Laboratories where he was involved in the design and implementation of systems for high-speed wireless packet communications. He has also served as a consultant with a number of companies focused on digital VLSI ASIC design and communication system design.
