摘要
在分析低密度校验码(LDPC)和Turbo码编码特性的基础上,将两种编码方案相结合,提出了一种新型的LDPC码--Tur-bo-LDPC码,并且把这种改进型编码应用到正交频分复用(OFDM)系统中。该编码方案综合了两种纠错编码算法的优点。理论分析和仿真实验显示这种新型编码方案能够改善OFDM系统的性能,具有一定的实用性。
Based on the combination of Low Density Parity Check(LDPC) code and Turbo code,is applied a new type of LDPC code--Turbo-LDPC code is proposed, and the improved coding scheme is applied to OFDM system. The scheme integrates the advantages of two kinds of error correction coding algorithm. Theoretical analysis and simulation experiments show that this new type of coding scheme improves the performance of OFDM system and has a certain practicality.
