Abstract :
In AWGN channel, the differential frequency hopping (DFH) system had a bad performance especially with low SNR. It firstly proved the DFH had the equivalent convolutional code structure, then analyzed and simulated the performance of Viterbi decoding algorithm in AWGN channel. Computer simulations indicate that the novel method could greatly improve the performance of DFH system in AWGN channel
