Mitigation of Impulsive Interference in Power Substation with Multi-Antenna Systems

Power substations constitute a unique environment where the wireless medium is corrupted by impulsive electromagnetic interference. Conventional receivers are designed to operate in typical environments where the noise is assumed to be a white Gaussian noise. Hence, using conventional receivers in power substation environments may result in poor performance. To design reliable communication system, we must consider a receiver that is more adapted to these particular environments. In this paper, we first start by extending a single antenna impulsive interference model to a multi-antenna scenario. Then, we introduce a new receiver that is more suitable to the studied environment. This receiver takes advantage of multi-antenna at the receiver side to mitigate the interference. Simulations show that using the proposed approach gives significant performance upgrade compared to the conventional Gaussian receiver.
