Adaptive digital filter-based narrowband interference canceler for CDMA system

摘要

We often encounter a situation where several half-duplex based narrow-band interferes give much damage to DS-CDMA signal with sudden changes in the power level. In this paper, we discuss a method to reject such narrow-band interference in DS-CDMA system. We propose an adaptive digital filter-based narrow-band interference canceler with an interference detection method. We show the rejection and detection performance obtained from computer simulation.
