摘要：

针对短波信道存在干扰严重的问题,提出一种高效的信道编码用于短波电台的编码模块。描述了短波电台RS码和卷积码的信道编码基本原理,对接近Shannon限的高效信道编码——Turbo码做了介绍,并对其进行计算机仿真和性能比较。仿真结果表明,Turbo码在低信噪比条件下具有较强的纠错能力,将其应用到短波通信系统中,有效地提高短波通信的抗干扰能力。

Abstract:

To deal with serious interference in HF radio channel,an efficient channel coding is proposed in this paper.The principles of RS codes and convolution codes usually used in HF radio are described,and Turbo code that is close to Shannon limit is introduced.Computer simulation and performance comparison is conducted.The simulation results show that Turbo code has strong error-correcting ability at low SNR,and it can effectively reject the interferences when applying it in HF communication system.

Key words: HF channel;RS code;convolution code;Turbo code
