It is also shown that the generalized Gray map image of (1- p~k)- cyclic is a distance invariant (not necessary linear) quasi-cyclic code.
也证叫了(1-p~k)-循环码在推广的Gray映射下的像是距离不变(不一定是线性的)的准循环码。

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。
This paper presents an algebra method for constructing LDPC code based on Vandermonde matrix, which includes quasi-cyclic Q matrix and the perfect cyclic difference sets.
