Low encoding complexity can also be achieved due to the inherent quasi-cyclic structure of the LDPC codes.
由于产生的LDPC码本身固有的准循环结构,还能得到较低的编码复杂度。

These quasi-cyclic LDPC can not only reduce the storage of LDPC generator matrix, but also decrease the encoding complexity efficiently, which is of great significance for the applications.
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.
