摘　　要：考虑到直接序列扩频(DS-SS)系统中无限深度格型陷波器在去除窄带干扰的同时对扩频信号的损伤,在无限深度格型陷波器上添加一自适应横向滤波器,其输出作为对受损扩频信号的误差补偿.仿真结果证实,新设计的误差补偿滤波器改善了无限深度格型陷波器的性能,而系统计算复杂度只有少量增加.Taking account of the fact that an infinite depth lattice notch filter damages spread spectrum （SS） signal as it excises the narrowband interference in a direct sequence spread spectrum （DS/SS） system, this paper introduced an adaptive transversal filter to infinite impulse response （IIR） lattice notch filter, and the output of the transversal filter is taken as the error compensation of the spread spectrum signal. The simulation results show that the proposed error compensation filter improves the performance of IIR lattice notch filter, and involves only a little more complexity.
