提出了一种用于低密度奇偶校验（LDPC）码译码的初始引导步骤。解码是通过首先擦除一些不太可靠的位来启动的。新的值和可靠性，然后分配给擦除位通过可靠的检查方程传递消息从nonerasure位。将引导步骤应用于加权位翻转算法以解码多个LDPC码。在性能和复杂性方面都有很大的改进。
An initial bootstrap step for the decoding of low-density parity-check (LDPC) codes is proposed. Decoding is initiated by first erasing a number of less reliable bits. New values and reliabilities are then assigned to erasure bits by passing messages from nonerasure bits through the reliable check equations. The bootstrap step is applied to the weighted bit-flipping algorithm to decode a number of LDPC codes. Large improvements in both performance and complexity are observed.
