| 摘 要： | 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总体特性要优于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。

| Abstract: | In this article, performances of Turbo codes and SCCC with (the number of memory) m=4 in component convolutional codes over AWGN channel is studied through simulation, and the performance comparison between Turbo codes and SCCC is carried out.Simulation results show that when m=4 ,the Turbo codes schemes give a very good performance compared to SCCC schemes.However, at high SNR performances of SCCC is better and avoids the floor effect, a disadvantage of Turbo codes. |
