摘要
本文研究了自适应非线性滤波在直扩通信中抑制窄带干扰的应用,修正了Vijayan和Poor所采用的抽头更新算法,使非线性滤波的性能明显改善。同时把自适应非线性横向滤波结构推广到Lattice结构,提高了收敛速度。
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.
