| Abstract: | In this paper the application of using adaptive nonlinear filter for narrow-band interference suppression is studied.The algorithm for updating the tap weights,which is proposed by Vijayan and Poor[9],is modified and the performance of the modified nonlinear filter is distinctly improved.In order to increase the convergence rate of nonlinear LMS filter an adaptive nonlinear lattice filter is proposed. |
