Sažetak
In this paper, MISO OFDM-CDMA downlink scheme is proposed as a solution for improving performance of the OFDM-CDMA downlink system with pilot tone and threshold detection combining (optimum TDC). The new presented system with MISO included uses space-time block coding applied to two and four transmit antennas. BER (Bit Error Rate) performance in the case of Ricean frequency selective fading is evaluated for the original system as well as for the one with MISO included. For that reason an adequate simulation model is developed. The results show that the proposed system significantly outperforms the OFDM-CDMA downlink system with pilot tone and optimum TDC.
