A MIMO approach for performance improvements of OFDM-CDMA system with pilot tone
In this paper, MIMO OFDM-CDMA downlink scheme is proposed as a solution for performance improvements of the OFDM-CDMA downlink system with pilot tone and threshold detection combining (optimum TDC). The new presented system with MIMO included uses space-time block coding applied to two, three 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 MIMO included. For that reason an adequate simulation model is developed. The results show that the proposed system significantly outperforms OFDM-CDMA system with pilot tone.
