摘要：
MIMO CDMA system with the calibration of OFDM method is proposed. To obtain the spatial diversity between the symbols, STBC block codes were used. Space time block coding (STBC) is the most efficient method due to its provision of full spatial diversity and simple linear decoder. The combination of space-time block coding (STBC) and Direct-Sequence Code-Division Multiple Access (CDMA) has the potential to increase the performance of multiple users in a cellular network. The BER performance of MIMO-CDMA system depends on its spreading strategy. In this paper MIMO-CDMA in calibration with OFDM system is designed with STBC matrices for spreading. The proposed technique outperforms the T-design permutation spreading method and also the conventional method. Simulation results show the gain improvement with STBC approach as compared to other existing techniques.
