Abstract
In this paper, we investigate the performance of bit interleaved coded multiple beamforming (BICMB). We
provide interleaver design criteria such that BICMB achieves full spatial multiplexing of min(N, M) and full
spatial diversity of NM with N transmit and M receive antennas over quasi-static Rayleigh flat fading channels.
If the channel is frequency selective, then BICMB is combined with OFDM (BICMB-OFDM) in order to combat
intersymbol interference (ISI) caused by the frequency selective channels. BICMB-OFDM achieves full spatial
multiplexing of min(N, M), while maintaining full spatial and frequency diversity of NML for an N ŚM system
over L-tap frequency selective channels when an appropriate convolutional code is used. Both systems analyzed
in this paper assume perfect channel state information both at the transmitter and the receiver. Simulation results
show that when the perfect channel state information assumption is satisfied, BICMB and BICMB-OFDM provide
substantial performance or complexity gains when compared to other spatial multiplexing and diversity systems.
