Progress Report on MIMO Research : Fall 2005

During Fall 2005, we investigated the performance of bit interleaved coded multiple beamforming with OFDM (BICMB-OFDM) for frequency selective channels. We provide interleaver design criteria such that the resulting system achieves full spatial multiplexing of min(N, M) and full spatial and frequency diversity of NML for a system with N transmit and M receive antennas over L-tap frequency selective channels when an appropriate convolutional code is used. Simulation results show that BICMB-OFDM provides substantial performance gain when compared to the best spatial multiplexing systems.
