| 摘 要： | 提出了一种基于Householder变换的快速自适应干扰抑制方法.利用Householder变换构建的广义旁瓣相消器下支路阻塞矩阵,可将期望信号完全阻塞,提高了最小均方误差算法的收敛性,获得了较高的输出信干噪比,并提高了GPS接收机的快速抗干扰性能.理论分析和性能仿真验证了该方法的优越性.

| Abstract: | The adaptive Generalized Sidelobe Canceller(GSC) always employs the least-mean-square(LMS) algorithm for weight adaptation.In the GPS receiver,real adaptive interference suppression can not be satisfied by this algorithm because of its slow convergence rate,especially at the very low signal-to-noise ratio(SNR).Since the convergence behavior of the LMS algorithm is highly dependent on the eigenvalue spreads of the covariance matrix of the blocking matrix output,we present a novel Householder-based fast adapt... |
