Abstract:

Linear dispersion codes(LDCs)were originally designed based on maximum likelihood detection. They do not have good performance when using ordered successive interference cancellation(OSIC)detection. In this paper, we propose a new improved linear dispersion codes transmission scheme to combat performance loss of original LDCs when using OSIC detection. We introduce an interleaver to each data substream transmitted over different antennas after LDCs encoder. Furthermore, a new computer search criterion for a linear transformation matrix is also proposed. New search criterion is to minimize the symbol error rate based on OSIC detection. Computer simulations show that the performance of proposed LDCs transmission scheme is better than the original LDCs.
