Aimed at the problems that the frequency hopping signal and the interference signal are delayed due to the processing time of the interfering signal and the distance between the jammer and the transmitter receiver, an adaptive cancellation technique based on algorithm superposition least mean square (LMS) algorithm is proposed. At the same time, on the basis of the theoretical analysis, the proposed improved LMS algorithm is applied to the FPGA platform for simulation experiments. Firstly, the adaptive algorithm simulation platform targeted by the frequency hopping signal and the interference signal is simulated by simulink simulation platform. Secondly, the original signal and the offset waveform are obtained by ISE software. Finally, the signaltointerference ratio is obtained by Matlab. The simulation results show that the algorithm is good in suppression effect.
