摘要
研究了非线性自适应滤波在直扩通信中抑制窄带干扰的性能，并用比扩频带宽窄的数字信号干扰模型进行计算机仿真，结果显示非线性自适应滤波对窄带干扰具有明显的抑制能力．
The performance for narrowband interference rejection of nonlinear adaptive filters in directsequence spreadspectrum (DSSS) systems is studied. By computer simulation with digital interference signal, bandwith of which is small in comparison to the spread signal, the results of analysis show that nonlinear adaptive filters have distinct capability to reject NB interference.
