摘要
本文根据LDPC的编译码原理,提出一种新颖的有利于硬件实现的编译码结构。这种译码结构采用准循环的编码构造方法,对于在计算和存储方面较为便利,采用简化的译码算法,硬件实现简单,且编码增益较高,所有的性能在BPSK调制和AWGN信道中得到估值。
According to the principle of LDPC coding and decoding, this paper presents a new coding-and-decoding structure convenient for hardware realization. This structure adopts quasi-cyclic structuring ways which are convenient for calculation and storage. Adopting simplified decoding algorithm, the hardware realization is relatively simple. Moreover, the coding plus is high. All the performances are evaluated over the AWGN channel with BPSK modulation.
