Novel image transmission system based on unequal error protection and dynamical sub-carrier allocation techniques

Fully considering the characteristics of transformed image data stream, Turbo codes and multiple carriers system, we propose a novel image transmission system based on unequal error protection and dynamical sub-carrier allocation techniques. This system utilizes unequal error protection (UEP) and dynamical sub-carrier allocation techniques to transmit different part of image data streams. For the critical part, we encode them with low rate Turbo code and choose high SNR sub-carriers to transmit them. Simulation results prove that this proposed sheme can effectively protect the important image stream and improve the image transmision performance over the noisy channel.
