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

Abstract

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.
