In this paper we propose a new method for designing the spreading permutations based on space time block code matrices for MIMO-CDMA systems. The new designs improve the bit error rate (BER) compared to MIMO-CDMA systems that use spreading permutations based on T-designs. This BER improvement comes without any increase in system complexity.
