Abstract

Multicarrier-code division multiple access (MC-CDMA) technique based wireless communications system provides robustness to frequency selective fading, high spectral efficiency, and flexibility to support multiple user with high data rate. In this paper, a comprehensive simulation study for the performance evaluation is undertaken of V-Blast encoded MIMO MC-CDMA wireless communication system in encrypted Color Image Transmission. The 4 ×4 multi antenna configured simulated system under investigation incorporates a combination of Minimum Mean Square Error (MMSE) and Zero-Forcing (ZF) signal detection techniques under different digital modulation schemes (BPSK, QPSK, and 16QAM). MATLAB based simulation study shows that V-Blast encoded system is very much robust and effective in retrieving encrypted color image under the utilization of ZF and MMSE signal detection and 16QAM digital modulation schemes.
