Mitigation Of Multiple Impulse Noise Sources Through Selective Attenuation

On modern military platforms, there are many electronic systems that can cause interference to other. In order to mitigate the performance degradation this cosite interference might cause, attenuation of the received power from the interference sources is needed. In this work, we propose simple methods to select appropriate attenuation values for multiple impulse noise sources. The methods are based on approximations of the total bit error probability (BEP), in order to determine the impact from each individual source on the total system performance. Different methods for approximating the resulting BEP, and thereafter selecting the appropriate attenuations, are proposed based on different levels of knowledge of the individual interference signals. Either the BEP as a function of receive SIR or the impulsiveness correction factors (ICFs) and average powers are assumed to be known for each individual interference signal. The proposed methods are evaluated numerically and perform well in different scenarios.
