摘要

根据差分跳频方案在相邻频率中获取数据信息的特点，结合turbo码的相关性，提出了一种基于turbo码的高速高频差分跳频系统。该系统充分利用了turbo码、DDS和DSP技术的优良性能。数值仿真结果表明，当AWGN信道和Rayleigh信道信噪比分别为0.2 dB和3.8 dB时，误码率可降至10/sup -5/，系统在部分频带干扰情况下仍能获得较好的可靠性。

A high speed HF frequency hopping system based on turbo codes

According to the characteristic of differential hopping frequency scheme that takes data information in adjacent frequencies and the correlation of the turbo codes, a high speed high frequency differential hopping frequency system based on turbo codes is presented in this paper. The system is designed by making good use of the excellent performance of turbo codes, DDS and DSP technology. The numeric simulation results show that when signal-to-noise is 0.2 dB and 3.8 dB in AWGN and Rayleigh channel respectively, the bit error rate could be reduced to 10/sup -5/, and the system could achieve a good reliability under partial-band jamming situation.
