According to the structure of Quasi-Cyclic LDPC code, we can make a trade-off between hardware complexity and decoding throughput by applying semi-parallel architecture.

利用准循环ldpc码的结构特点，使用半并行结构的译码器可以实现复杂度和译码速率的有效折中。

The cyclic code based on pseudorandom sequence, and its decoding can take advantage of the nice characteristic of pseudorandom sequence's correlation.

构造一类具有伪随机序列性质的循环码，并利用良好的伪随机序列的相关特性，对循环码进行相关译码。
