摘　　要：针对短波无线通信的特点,分析了其天波和地波的传播原理和特征,其易受多路径、多普勒效应和衰减影响。为提升短波信道质量,文中重点介绍了Turbo编译码结构,利用RS码在突发差错方面的较强校正能力,将其与Turbo码相结合,提出基于RS-Turbo级联码的纠错算法,将其应用于短波编译码和纠错技术中,达到降低短波通信误码率的目的。According to the characteristics of short wave wireless communication,the propagation principle and characteristics of sky wave and ground wave are analyzed,which are easily affected by multipath,Doppler effect and attenuation.In order to improve the quality of HF channel,this paper focuses on the structure of turbo coding and decoding.By combining RS code with turbo code,an error correction algorithm based on RS turbo concatenated code is proposed,which is applied to shortwave coding and error correction technology,so as to reduce the bit error rate of HF communication.
