Color Image Transmission: Error Analysis of a Concatenated FEC Scheme Based OFDM System

Orthogonal Frequency Division Multiplexing (OFDM) systems have become popular recently for providing high data rate multimedia services over severe multipath channels which can offer high speed voice, video and data service up to the customer end. In this study, the performance of a concatenated interleaved FEC (Forward Error Correction) scheme based OFDM communication system on digital image transmission under different combinations of digital modulation (BPSK, QPSK, 4-QAM and 16-QAM) over both Additive White Gaussian Noise (AWGN) and fading (Rician and Rayleigh) channels have been discussed. The simulation study is made with the processing of a color digital image under AWGN and different fading channels. It is observed from the simulation study that the modulation technique used is robust in discrimination of the transmitted digital image in both AWGN and fading environments.
