摘要

In this study impact of concatenated block code (RS, BCH, Cyclic code) and interleaver with Space Time Trellis Code (STTC) on the performance of a Multiple-Input Multiple-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) wireless communication system on color image transmission has been investigated. The MIMO-OFDM system incorporates two digital modulations (QPSK, QAM) over an Additative White Gaussian Noise (AWGN) and other fading (Raleigh and Rician) channels for two transmit and two receive antennas. It implements Minimum Mean-Square-Error (MMSE) channel equalization technique is highly effective to combat inherent interferences under Rayleigh, Racian fading and Additive White Gaussian Noise (AWGN) channel. The transmitted color image is found to have retrieved effectively under noisy and fading situations. It has also been anticipated that the performance of the communication system degrades with the increasing of noise power.
