| 摘 要： | 由于无线信道存在多种衰落,无线通信系统在含有随机错误的同时,还含有大量的突发错误.为了纠正这样的混合错误,常引入具有较强抗突发错误能力的RS编译码技术.Turbo乘积码也有着较强的随机纠错性能,但目前关于其混合纠错能力方面的研究还较为少见.在分析Turbo乘积码突发纠错能力的基础上,将突发错误参数对TPC纠正混合错误性能的影响进行仿真分析,并与相同码率、相同码长的RS码进行对比.仿真结果表明,Turbo乘积码在BER为10 4处可以获得近3.5 dB的编码增益,这意味着节省近55%的码元能量,是一种适合于解决混合错误的差错控制编码技术.

| Abstract: | Because of various fading modes in wireless channel,there are both random and burst errors in wireless communication systems.To correct the errors,reed-solomon(RS) codes are often considered.Turbo product code has also a strong random error correction performance,but the study of its hybrid error correction capability has rarely been reported at present.Based on the analysis of burst error performance of turbo product code(TPC),simulations of TPC with burst error parameters were performed,and the results were compared with RS code at the same rate and the same code length.It is shown when BER is,TPC outperforms RS code,and it can be near 3.5 dB.It means 55% bit energy is saved.Hence,TPC is a suitable solution for error-correction codes for hybrid errors. |
