Abstract

Abstract

In this paper the error-correcting performance of frequency transition function for Differential Frequency Hopping （DFH） communication system is analyzed first. Then a Viterbi algorithm is proposed and applied to frequency sequence decoding of DFH receiver, and it is further improved by the full use of the characteristics of transition function. The decoding performance of Viterbi algorithm is analyzed with the requirement that the transition function should achieve the best error-correcting performance. Simulation results show that 5- 8dB gain could be achieved for stochastic frequency detection error when SNR is low.
