| Abstract: | In this work, we propose a new block based quasi-orthogonal space-time block encoding and decoding (QO-STBC) scheme for a wireless system with four transmit antennas in frequency selective fading channels. The proposed scheme effectively combats channel dispersion and frequency selectivity due to multipath, yet still provides full diversity gain. We also proposed a maximum likelihood (ML) detector for decoding the block based QO-STBC symbols, that has a very simple decoupled structure and achieves the ML performance at low complexity for channels with short delay. | ||
