基于Huffman信源编码和LDPC信道编码的联合译码算法
Joint Source-Channel Decoding of Huffman Codes with LDPC Codes
在本文中，我们利用Huffman编码后的信源冗余，为LDPC码提出了一个联合译码算法。当Huffman码字数增加时，我们仅需要增大一个查询表，该查询表用来信源冗余来估计信息比特，这样仅仅需要增加较少的译码的复杂度
In this paper, we present a joint source-channel decoding algorithm (JSCD) for LDPC codes by exploiting the redundancy of the Huffman coded sources.When the number of Huffman codes increases, just a moderate complexity is added for our algorithm by increasing the size of the lookup table, which is used to estimate the information bit probability based on the source redundancy.
