Abstract: According to the characteristic of differential frequency hopping, this paper presents a nonbinary convolutional code equivalent model of G function and the design of optium receiver for differential frequency hopping signal. The paper also studies two maxium-likelihood detect algorithms (Viterbi hard-decision detection algorithm and Viterbi soft-decision algorithm) and computer simulations indicate that the maxium-likelihood method can greatly improves performance of differential frequency hopping system for AWGN channel.Finally,the realization of Viterbi hard-decision detection algorithm is described.
