Abstract

This paper presents a suppression method for the interference characterized by constant amplitude and polynomial phase signal (PPS) based on high-order instantaneous moment iterative approach in direct-sequence spread spectrum communication. The phase parameters of polynomial phase interference are accurately estimated based on high-order instantaneous moment and iterative approach, and the interference amplitudes is estimated by least-square algorithm, then the interference from received signals is synthesized by estimated parameters. The interference contribution can be removed by subtracting synthesized interference from received signals in time domain. Simulation results show that the performance of interference suppression is greatly improved.
