This paper presents a joint source-channel coding scheme based on SPIHT (Set partitioning in Hierarchical trees) algorithm and LDPC(Lower Density Parity Check) codes?Taking full advantage of the characteristics of SPIHT algorithm and LDPC Codes?The scheme of UEP (unequal error protection) is adopted in channel coding based on compressed data according to the importance for reconstruction?The results show that the proposed scheme can make a better balance between bit error rate and code rate?
