Abstract: In this paper, we address the problem of narrowband interference suppression in direct-sequence spread spectrum (DSSS) systems. Specifically, we present a new method for improving the performance of DSSS systems employing narrowband interference rejection filtering. The proposed method is based on the idea of restoring the distorted DS signal at the interference rejection filter's output. The restoration process is accomplished by using a maximum-likelihood sequence estimator. Bit error rate of a receiver that employs such a structure is examined.
