This paper has researched the effect of hop-rate in the FH anti-jamming system based on CVSD coding.It presents the principle of CVSD coding and the model of SFH,suggests the rule for measuring speech signal's quality and the method of how to simulate the FH system with baseband model,and points out the optimized parameters selecting of CVSD coding.In the end,the paper analyses the performance of FH system with different Frequency-Hopping rates on the part-band-noise jamming channel,and makes a conclusion.
