摘要：Frequency-hopping communication has the capability to resist narrowband interference, which is in direct proportion to the hopping rate. In frequency-hopping system, interference signals exist in partial de-hopping frequency-hopping signals, equivalent to time-varying interference signals existed in the frequency-hopping signals. Through integrating the diversity combining techniques of fast frequency-hopping communication with singular value decomposition method, this paper detects the frequency-hopping points, masks them, and then combines with undisturbed frequency- hopping signals. MATLAB simulation shows that narrowband interference is well restrained and the system BER is obviously improved.
