摘要

构造了一类用于II型H-ARQ系统、具有Z字形结构校验矩阵、性能优良的速率可变低密度校验码(RC-LDPC)。将渐进边增长(progressiveedgegrowth)算法推广应用到RC-LDPC码的构造中

扩大了码率动态变化范围

提高了码的性能。仿真结果表明将此类RC-LDPC码应用于II型H-ARQ系统

可获得较高的吞吐量

且其校验矩阵的Z字形结构极大地降低了系统实现的复杂度。

Abstract

The design of powerful rate-compatible low-density parity-check codes（RC-LDPC）was constructed in zigzag structure for type-II hybrid ARQ systems.The generalized PEG algorithm was used in the process of constructing RC-LDPC codes to improve the performance of the proposed codes.Simulation results show that based on constructed RC-LDPC codes

a type-II hybrid ARQ system can achieve efficient throughput.In addition

very low-complexity encoding and decoding rules can be implemented due to the overall zigzag structure of these RC-LDPC codes.
