In this paper, we propose an optimal bit allocation method for MPEG-4 fine granularity scalable (FGS) video over OFDM transmission. In the proposed method, we consider the joint optimal bit allocation of source and forward error correction (Reed-Solomon) codes of different rates over OFDM. Our simulation results show that our proposed approach achieves significant PSNR gain over the existing approach without channel error protection when the input and the output data rates are fixed.
