| 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. |

| Keywords: | HF channel RS code convolution code Turbo code |
