MC-CDMA MIMO Spatial Multiplexing Technique for High Data Rate Mobile Transmission

With the increasing demand of High data transmission in 4G/LTE(Long Term Evolution) mobile communication networks has dramatically becoming an important distinguished requirement field recently; and the rapid growth in traffic volume in business services has begun to transform the configuration and structure of wireless networks. The need of highness techniques should be considered as optimum solution to resolve the inadequate problem observed in multiuser diversity communication systems. For this observation, multi-antenna techniques can be used to achieve improved system performance, including improved system capacity and improved coverage, as well as improved service provisioning. In this paper, after review and making comparison with main current performed (QR-ML, IC-MMSE and IC-ZF receivers) high transmission technique, we propose a novel MC-CDMA MIMO Spatial Multiplexing system based on Alamouti's STBC and combined to V-BLAST code to improve the signal-to-noise/interference ration and significantly higher data rates over the radio interference. By using MATLAB software for simulation, results shows that the efficiency of signal can be increased and an 11dB for a minimum of three antennas can be obtained.
