Abstract
In order to solve the electromagnetic interference happened in communication radio, the interference suppression method based on adaptive interference cancellation is used to suppress the intraband interference.This paper introduces the principle of adaptive interference cancellation and Gaussian minimum frequency⁃shift keying (GMSK).Based on simulink,the frequency hopping radio model and the radio model containing AIC are set up. In the simulation, the BER under different SNR of white noise, constant frequency interference and comb interference before or after the cancellation is obtained by changing interference types. The simulation results show that the communication performance is vulnerable to comb interference,and the interference effect is more obvious than the constant frequency interference and white noise.It is effective for interference suppression after AIC adding to the simulation.关键词
