Abstract：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.
