| Abstract: | An adaptive beamforming algorithm based on LCMV algorithm is studied in this paper.Combined with the feature of the GPS satellite signal,this algorithm is applied in anti-jamming system of GPS receiver.The adaptive algorithm is derived in detail,and the simulation models of these two algorithms are constructed in MATLAB.The results show that the proposed adaptive algorithm can retain the desired GPS signal while suppressing the interference signal. |
