摘要：In this paper, a comprehensive BER performance simulative study has been made on secure color image transmission in a SC-FDMA wireless communication system. The system implements a modified form of Chaos-based image encryption scheme under utilization of three channel equalization techniques (MMSE, ZF and Q-Less QR Decomposition) and three digital modulation schemes (QPSK, DQPSK and QAM).In comparative study, it is noticeable from simulation results that the ½-rated convolutionally encoded system combined with both transmit and receive diversity in Rayleigh multipath fading channel outperforms in QAM and ZF schemes.
