Abstract:
In this paper on MIMO-CDMA systems employing permutation spreading, we propose a new method for designing the spreading permutations based on space time block code matrices. We investigate the bit error rate performance of these systems using BPSK and QPSK modulation in single and multiple user situations. The new designs provide full transmit diversity between different message cosets. Compared with spreading permutation designs based on T-designs, the STBC-based spreading permutation designs improve the bit error rate performance without any increase in system complexity.
