Abstract :
In this paper, we consider the transmission of progressive image data over noisy channels with the protection of rate-compatible punctured turbo codes (RCPT) concatenated with multiple cyclic redundancy check (CRC) codes. To optimally allocate the given bandwidth resource for unequal error protection (UEP), a genetic algorithm (GA) based method is proposed to reduce the optimization complexity. In addition, a structure of multiple CRC blocks is employed in some data packets so that more correctly decoded data could be used in decoding. Simulation has demonstrated promising results of the proposed scheme
