In this paper, we propose Layered Turbo codes on MIMO channels with multiple transmit and receive antennas. We consider some coded layered space-time code architectures on flat Rayleigh fading quasi-static channels, and evaluate its BER performance by computer simulation. At the transmitter, the data streams are encoded by multiple turbo codes which consist of parallel concatenation of convolutional codes, then transmitted to the MIMO channel through the V-BLAST architecture. At the receiver, each received signals are detected by low-complexity interference cancellation algorithm based on MMSE criteria with perfect CSI, and soft detected outputs from the V-BLAST detector are delivered to the turbo decoder.
