基于扩域分组的多码率QC-LDPC码设计
Design of multi-code rate QC-LDPC based on extension field grouping
摘要
Abstract
Some basic characteristics of Galois Field are analyzed. At the same time, some basic methods for constructing Quasi Cycle Low Density Parity Check (QC-LDPC) codes are presented. A method of constructing QC-LDPC codes based on Grouping of Galois Field's Extension Field can be realized. By grouping Galois Extension Field's linear independent elements, the QC-LDPC codes with different rates can be easily constructed. Simulation results show that under 10-5 BER, our method has almost the same performance as codes constructed based on dayan sequence, the latter has 0. 1 dB more gain than the former. Compared with codes constructed based on Fibonacci sequence, our method has 0. 8 dB more gain. Our method has 1 dB gain less than the method proposed by IEEE802. 16e standard. It still has large space to improve the method.关键词
