Images are transmitted wirelessly for different purposes- where the most widely used reason is for multimedia communications. Another use is for detailed and vital information transmission. In this work, I have shown that even though an image is visually appealing, it might still be missing some information content. Effective means of digital image transmission by means of Forward Error Correcting (FEC) schemes and Orthogonal Frequency Division Multiplexing (OFDM) is presented in this paper. The transmission was simulated over the AWGN and a Rayleigh fading channel whose power delay profile was adopted from the ITU channel model. The FEC and OFDM parameters were adopted from the WiMAX standard. The results presented herein are in terms of BER, PSNR, image entropy and visual performances. It is evident from the presented results that effective FEC schemes are necessary for reliable transmission of digital media in a mobile wireless scenario, the results reveal that from an information theory point of view, RS-CC coding is an insufficient method of FEC due to its limitation in overcoming the problem of error floor formation.
