摘要:

研究了一种基于LCMV算法的自适应波束形成算法。结合GPS卫星信号的特点将该算法应用于GPS接收机的抗干扰系统中。文中对该自适应算法进行了推导和Matlab仿真,并使之与LCMV算法的仿真效果作比较,结果表明,该算法能更好地抑制干扰、保留期望信号。

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.
