Abstract :
In this paper, bit error rate (BER) performance of the MIMO OFDM-CDMA system, in case of Ricean frequency selective fading, is evaluated using originally developed computer simulation. The assumed system uses space-time block coding applied to two, three and four transmit antennas and has arbitrary number of receive antennas. Channel estimation is performed by implementing pilot sequences at each transmit antenna. The results are compared with BER results of the competitive OFDM-CDMA down link system with threshold detection combining (optimum TDC). The results show that the presented system provides lower BER, even when less subcarriers are used for transmitting single data symbol, than its competitive solution.
