Abstract :
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 10-5, and the system could achieve a good reliability under partial-band jamming situation.
