Abstract

Wireless communication using multiple-input multiple-output (MIMO) systems enables increased data rates and link reliability for a given total transmit power and system bandwidth. Increased capacity is achieved by introducing additional spatial channels which are exploited using space-time coding. The spatial diversity improves the link reliability by reducing the adverse effects of link fading and shadowing. Because antenna arrays are used at both the transmitter and receiver, interference can be mitigated naturally. In this paper, MIMO communication is investigated using outdoor experimental data collected near the PCS frequency allocation (1790 MHz) in the presence of multiple jammers. Coherence issues associated with implementing antenna arrays using ad hoc groups of users are addressed. Presented here is an experimental example of demodulation of a space-time turbo code using a multichannel multiuser detector (MCMUD) that compensates for delay and Doppler spread, as well as local oscillator mismatch. In the experimental data the MIMO signal is transmitted from a moving vehicle.
