| 摘 要： | 针对CCSDS推荐的(8176,7154)有限几何准循环LDPC码,研究了LDPC码的修正最小和译码算法,提出了一种新的动态补偿最小和译码算法,并将本算法和修正最小和译码算法进行了性能比较。仿真结果显示,动态补偿最小和译码虽然算法迭代的收敛速度有所减慢,但具有比修正最小和算法更好的误码性能。

| Abstract: | With regard to （8176, 7154） finite geometry-based QC-LDPC code recommended by CCSDS standard, this paper introduces the modified min-sum algorithm of LDPC codes, and a new dynamic compensation decoding algorithm is presented. The simulation compares the new decoding algorithm with modified min-sum algorithm. As the result shows, although dynamic decodingalgorithmletstheconvergence speedofiterationalittledown, butexhibitsbetterperformaneethanmodifiedmirssumalgorithm . |
