Abstract :
According to the characteristic of differential hopping frequency scheme that taking data information in adjacent frequencies and the correlation of the turbo codes, a high-speed HF differential hopping frequency system is presented in this paper. The system is implemented by making good use of turbo codes and software radio 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. The system could also achieve a good reliability under partial-band jamming situation.
