摘要

最近引入了使用时频分布(TFD)消除扩频通信系统中的输入数据干扰以减轻非稳态干扰。干扰器的瞬时频率(IF)被估计并用于构建一个时变的0 m x图1块d，其中干扰去除(BER)随偏置的增加而增加，并且依赖于干扰器的IF。

Performance Spectrum Analysis Of Interference Excisions In Spread Communications Based On Instantaneous Frequency Estimation

Excision Filter-"-ii, Input data Interference excision in spread spectrum communication systems using time-frequency distributions (TFD) has been recently introduced to mitigate nonstation-ary interferers. The jammer instantaneous frequency (IF) is estimated and used to construct a time-varying 0 m x Fig.l block d i a g " of the interference excision (BER) increases with the bias and is dependent on the jammer IF.
