| 摘 要： | 基于现有的Turbo乘积码的编译码方法,提出一种附加删余的Turbo乘积码编译码算法,介绍其编码器的构造方法,阐述了译码算法及实现框图,分析了删余信息对传输帧长的影响,仿真了其误码性能,并与未删余的Turbo乘积码做比较。分析和仿真结果表明,附加删余的Turbo乘积码可满足特定系统传输速率及帧长的需要,在相同的信噪比下,删余Turbo乘积码的误码性能优于未加删余的误码性能。

| Abstract: | Based on the current Turbo product code,an encoding and decoding algorithm for erasure Turbo product code is proposed and a method to construct Turbo product code is introduced.The decoding algorithm and block diagram are presented,and the influence on length of frame is analyzed.Moreover,the BER performance is simulated and compared with the traditional Turbo product code.The results show that,erasure Turbo product code can meet the requirements for the data rate and the length of the frame,and compared to... |
