چکیده
Frequency-hopping communication is widely used in the field of military communication, which has the capability to resist interference. In frequency-hopping system, narrowband interference signals exist in partial dehopping frequency-hopping signals, equivalent to time-varying interference signals existed in the frequency-hopping signals. Through integrating the diversity combining with singular value decomposition method, this paper detects the frequency-hopping points and then combines with undisturbed frequency-hopping signals. MATLAB simulation shows that narrowband interference is well restrained and the system BER is obviously improved.
