Performance Analysis of Encrypted Color Image in a D-BLAST Aided LDPC Encoded MC-CDMA Wireless Communication System

摘要

In this paper, a comprehensive MATLAB simulation based study has been presented for the performance evaluation of LDPC encoded MC-CDMA wireless communication system. The investigated system implements various signal detection techniques such as Minimum mean square error (MMSE), Zero-Forcing (ZF), Zero-Forcing successive interference cancellation (ZF-SIC) Minimum mean square error successive interference cancellation (MMSE-SIC) under different digital modulation schemes (QPSK, DPSK, QAM). Simulation results show that the system shows quite satisfactory and robust performance under scenario of MMSC-SIC signal detection and QAM digital modulation schemes.
