CDMA with MIMO is very good technique beyond 3Gand 4G wireless communications. CDMA with MIMO systemsgive large capacitive gains and good spatial diversity. Spatialdiversity and spatial multiplexing are two main aspects to betaken into consideration while designing communication system.STBC block codes can be used to obtain the spatial diversitybetween the symbols. Space time block coding (STBC) is themost efficient method because it provides full spatial diversityand simple linear decoder. If STBC and Direct-Sequence CodeDivision Multiple Access (CDMA) are combined, theperformance of multiple users in a cellular network is increased.The BER performance of MIMO-CDMA system depends on itsspreading strategy also. System performance can be furtherincreased by adding coding techniques. Forward ErrorCorrection codes can be used to that minimizes the errorprobability in decoding by adding the redundant bitssystematically. Here review of different techniques reducing BERis presented for CDMA MIMO system.
