Abstract
The BF decoding algorithm for LDPC codes is simple. However, if the number of burst errors is bigger than which BF algorithm can process, the decoding may fail. Interleaving technology is a kind of effective techniques to handle burst errors. Under this technology, consecutive errors in one codeword can be dispersed into multiple code words, therefore the number of errors in each codeword may be lower and in the range of processing ability of BF algorithm. Thence the interleaving technology in decoding can reduce the probability of correction failing and improve the transmission performance. In this paper, a class of burst channel has been studied and the interleaving is applied for data transmission. Simulation results show that the use of interleaving techniques can effectively reduce error rate.
