| 摘 要： | 针对删除信道中发生错误的数据包,提出联合信道编码的LBCMP迭代纠错方法,该方法充分利用错误数据包中含有的正确信息,将LT编码包作为冗余纠错包与线性分组码相结合,并采用MP迭代译码方法进行纠错.理论分析及实验结果表明,采用LBCMP迭代方法可以减少为恢复错误数据包所需要的信源编码包数量.

| Abstract: | Due to the problem of error data packets in erasure channel, line block code message propagation(LBCMP)iteration error correction scheme is proposed.This scheme is a combination of linear block code and LT codes.By taking Luby Transform(LT)encoding packets as the redundant correcting packets, it makes use of the correct symbol of linear block code to recover all error packets with elimination method.Our analysis and experiments show that LBCMP iteration error correction scheme reduces the encoding packets of the source for recovering all errors. |
