Performance Analysis of Multiple Input Multiple Output (MIMO) Multi-Carrier Code-Division Multiple Access (MC-CDMA) Combined with Quasi-Orthogonal Space Time Block Coding (QO-STBC) in Rayleigh Fading Channel

The need for a communication system with higher data rate and mobility grows along information technology development. Combining MC-CDMA the MIMO supporting good transmit diversity technique is promising idea to provide needed system, especially in high conditions. can support ubiquitous communications without affecting achievable BER more capable of high-speed mobility. It integrates benefit both OFDM CDMA. On other hand, QO-STBC increases bit using additional bandwidth system. So, this study proposed combining QO-STBC. investigated under conditions see system's performance. simulation results show that our performs better than STBC QOSTBC but not multilevel coding scheme. To reach value 10−3, Coding requires less power, around 5 dB,
