摘要: 研究一種基于LTJ結(jié)構(gòu)的自適應(yīng)非線性濾波器,討論了這種濾波器在CDMA衛(wèi)星通信中窄帶干擾抑制方 面的應(yīng)用。LTJ結(jié)構(gòu)的濾波器混合采用了Lattice和LMS兩種濾波器結(jié)構(gòu),結(jié)合了這兩種濾波器的優(yōu)點(diǎn),提高了收 斂速度,同時(shí)減小了濾波器的復(fù)雜度。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.
