Abstract :
We study the low complexity space-time turbo detection and decoding schemes for MIMO block transmission systems such as cyclic prefix based single-carrier block transmission (CP-SCBT) system and OFDM system. Because of the circulant property of the channel matrices, the detectors can he implemented by FFT/IFFT. Simulation results show that the proposed receivers significantly outperform the traditional, non-iterative receivers.
