查询词典 decoder

The paper describes a new iterative decoding algorithm for the product codes, its feedback method is completed by a linear combination of soft output of encoder and the receipt information is different with the traditional turbo iterative decode. When decoder obtains the soft output matrix built -1 and +1, the complexity can be reduced greatly and the performance can be lost utile by reducing the number of candidate code words and omitting the complicated operation of LLR.

针对乘积码提出一种新的迭代解码算法，该算法的反馈方式有别於Turbo码的传统迭代译码，是通过输出软信息与接收软信息进行线性叠加来实现的，此时子译码器的候选码字个数将大为降低，同时译码输出也无须做复杂的LLR计算，直接映射为由-1，+1组成的软输出矩阵，从而在牺牲较小性能的情况下很大程度地降低了译码复杂度。
