We repeat the rate 31/200 LDPC code for 10 times and get a rate 31/2000 low rate code. Comparing with our low rate code with CT algorithm decoding, the simulation shows it has 2dB better performance.
LDPC码在高码率( > 0.1)时性能很好,我们将码率为31/200的LDPC码经10次重复后得到码率为31/2000的低码率码,与CT算法比较,仿真结果显示,CT算法差约2dB ,这是因为CT算法为硬判决算法而LDPC使用了软判决译码算法。
