Abstract

Multiple Input - Multiple Output (MIMO) is a new communications paradigm which brings significant benefits to future communication systems. In contrast to conventional wireless communication systems, MIMO systems exploit the spatial diversity available in multipath propagation to create parallel channels within a common bandwidth. The multiple channels can be used for capacity enhancement, coverage improvement, lower radiated power spectral density, interference/jammer suppression, multi-beam communication and battery power savings. Research, development and exploitation of MIMO technology for tactical communication systems is significantly limited by lack of mobile, real-time MIMO testbeds to verify and validate extensive theoretical results. We report a 4x4 mobile, wideband, real-time MIMO-OFDM testbed designed and developed by the team of San Diego Research Center (SDRC) and Brigham Young University (BYU). Using this testbed we have successfully demonstrated the feasibility of peer-to-peer Mobile MIMO by closing 1000m links, at 50 mph speeds, at 12 bps/Hz spectral efficiency.
