Phase-locked loop application for simple periodic interference suppression in direct sequence systems

Abstract

The problem of simple periodic interference suppression in DS-SS (Direct Sequence Spread Spectrum) systems is considered. It can be solved using the method of phase-locked loop, transverse filters and adaptive arrays. The paper analyses the method of phase-locked loop by which a desired useful signal to simple periodic interference strength ratio can be obtained.
