摘要

本文研究了在AWGN和多径瑞利衰落信道中100mbps OFCDM(正交频码分复用)中已知turbo码插入方案的PER和吞吐量性能。通过用插入的已知位替换信息位来降低信息率的方法1使吞吐量增加8%。通过改变插入的已知比特数，使信息率与插入的已知比特数无关，从而得到固定的总FEC编码率的方法2，在优化插入的已知比特数时，与没有插入已知比特的传统turbo码相比，PER和BER都有了提高。

Packet error rate analysis and its reduction by known bits insertion for turbo code in 10OMbps OFCDM system

This paper investigated the PER and throughput performance of known bits insertion scheme for turbo code in 100 Mbps OFCDM(orthogonal frequency and code division multiplexing) in AWGN and multipath Rayleigh fading channels. The method 1 in which the information rate is reduced by replacing information bits by inserted known bits gives 8% throughput increase. The method 2 in which the information rate is fixed irrespectively of the number of inserted known bits by changing the number of punctured bits in order to get the fixed total FEC coding rate also gives PER and BER improvement compared with the conventional turbo code without known bits insertion when the number of inserted known bits are optimized.
