An Interference Identification Algorithm for Electric Energy Data Acquire System

Wireless communication network is a key component of Electric Energy Data Acquire System. With the increasingly complicated communication environment, it is essential to detect the Interference introduced by other systems and provide the priori information for the Subsequent interference suppression. Traditional interference detection algorithms generally only can determine whether the interference is present, or it is able to determine the type of interference, but the computational complexity is high. To solve the above problems, this paper presents an interference detection algorithm, which use the spatial correlation and the time domain correlation of interference signals to determine the existence of interference and the type of interference, respectively. This algorithm has the characteristics of low computational complexity, and the simulation results show that the algorithm can achieve good performance of interference detection.
