摘要
本文分析了非线性滤波在直扩通信中抑制窄带干扰的性能，推导了其性能改善的闭合表达式。并与相应的线性滤波的性能进行了比较，结果显示非线性滤波的性能要优于线性滤波。
The performance for narrow-band interference rejection of nonlinear prediction filters in direct-sequence spread-spectrum (DS-SS) systems is analyzed and the closed-form expressions for performance improvement are derived. The analysis results show that nonlinear prediction filters outperform linear ones by comparison.
