摘要
研究一种基于LTJ结构的自适应非线性滤波器,讨论了这种滤波器在CDMA卫星通信中窄带干扰抑制方 面的应用。LTJ结构的滤波器混合采用了Lattice和LMS两种滤波器结构,结合了这两种滤波器的优点,提高了收 敛速度,同时减小了滤波器的复杂度。
In this paper, a LTJ-based adaptive nonlinear filter and the application for narrowband interference suppression in satellite CDMA communication systems is researched. The filter based on LTJ structure used both Lattice and LMS adaptive structures, having the merit of these two filters. With this merit, the filter increases the convergence rate combining with decreasing the complexity of itself.
