JOINT SOURCE-CHANNEL DECODING OF HUFFMAN CODES WITH LDPC CODES
In this paper, we present a Joint Source-Channel Decoding algorithm （JSCD） for Low-Density Parity Check （LDPC） codes by modifying the Sum-Product Algorithm （SPA） to account for the source redundancy, which results from the neighbouring Huffman coded bits. Simulations demonstrate that in the presence...

| description | In this paper, we present a Joint Source-Channel Decoding algorithm （JSCD） for Low-Density Parity Check （LDPC） codes by modifying the Sum-Product Algorithm （SPA） to account for the source redundancy, which results from the neighbouring Huffman coded bits. Simulations demonstrate that in the presence of source redundancy, the proposed algorithm gives better performance than the Separate Source and Channel Decoding algorithm （SSCD）. |
