  • 摘要:Now a days, the demand for wireless communication systems with high data rates and high capacity has dramatically increased. CDMA (Code Division Multiple access) plays an important role in modern wireless communication systems. MIMO refers to links with multiple antennas at the transmitter and receiver side. CDMA with MIMO is a very promising technique beyond 3G and 4G wireless communications. The BER performance of MIMO-CDMA system depends on its spreading strategy. In this paper MIMO-CDMA system is designed with STB C (Space-Time Block Code) matrices for spreading. The proposed technique outperforms the t-design permutation spreading method and also the conventional method. Simulation results shows that gain improvement with STBC approach as compared to other existing techniques.
