JOINT SOURCE-CHANNEL DECODING OF HUFFMAN CODES WITH LDPC CODES被引量:1
《Journal of Electronics(China)》2006年第6期806-809,共4页Mei Zhonghui Wu Lenan 
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 redun-dancy, which results fr...

A CLASS OF LDPC CODE'S CONSTRUCTION BASED ON AN ITERATIVE RANDOM METHOD
《Journal of Electronics(China)》2006年第1期124-127,共4页Huang Zhonghu Shen Lianfeng 
Supported by the National Natural Science Foundation of China(No.60472053)
This letter gives a random construction for Low Density Parity Check (LDPC) codes, which uses an iterative algorithm to avoid short cycles in the Tanner graph. The construction method has great flexible choice in LDPC...
