Abstract

Narrow band interference can lead to severe performance degradation for direct sequence spread spectrum (DSSS) communication systems. In this paper, we propose a residual interference mitigation technique for frequency-domain interference suppression. By analyzing the effect of frequency-domain interference suppression, we model the residual interference as random process following Gaussian mixture distribution, and perform mitigation based on the locally most powerful (LMP) detector. The parameters are then estimated using the expectation-maximization framework. Finally, we analyze the performance of the proposed method, and illustrate the performance via numerical simulations.
