Abstract :
In this paper, we propose a scheme to design unequal error protection low-density parity-check (UEP-LDPC) codes based on Gaussian approximation algorithm over AWGN channel. Using this method, we can find effective UEP-LDPC code ensemble which has good overall performance and good UEP property. Simulation results show the superiority of the proposed UEP-LDPC code in improving the quality of reconstructed image in uncompressed image and set partitioning into hierarchical trees (SPIHT) coded image transmission.
