摘要
本文详细介绍了Turbo码与SCCC的基本编译码原理,并通过仿真,研究了基于AWGN信道,分量码约束度m=4的条件下,Turbo码与SCCC各自的性能,并对两者进行了比较。仿真结果表明:当m=4时,Turbo码系统的BER特性总体要优于SCCC,但在高信噪比时,SCCC的性能比较好,而且避免了地板效应这一Turbo码的典型缺陷。
In this article, the basic principles of encoding and decoding of Turbo codes and SCCC are introduced in detail, and performance of Turbo codes and SCCC with m=4 in component convolutional codes over AWCN channel is investigated through simulation, and the performance comparison between Turbo codes and SCCC is carried out.Simulation results show that when mr4 ,the Turbo codes schemes give a very good performance compared to SCCC schemes.However, at high SNR performances of SCCC is better and avoid the floor effect, a disadvantage of Turbo codes.
