Abstract

Space-time bit-interleaved coded multilevel modulation over frequency-selective multiple-input multiple-output (MIMO) fading channels is considered. The receiver is turbo based. A soft-input soft-output (SISO) space-time fractionally spaced equalizer is designed for the minimum mean square error (MMSE) criterion. Simulation results show the ability of the receiver to account for intersymbol interference, co-antenna interference, and its capability to exploit transmit, multipath, and receive diversity. These results are also compared to a bit-error-rate lower bound.
