Mitigating the Aperiodic Impulsive Noise in PLC –Power Line Communication - Communications Improves Efficiency and is an Alternative in Data Transmission

Abstract

Throughout the history of telecommunications, the noise has been considered one of the main setbacks in the communication process of any system, causing loss of information and thus having a direct impact on system reliability. In a PLC communication system, the electrical disturbances that interfere with the signals to be transmitted become more relevant compared to other systems given that the electric network is not the most suitable channel to send data. The modeling process discussed in this document uses statistic-based tools such as the Middleton model and several experiments to determine the appearance of noise within the spectrum and how it can be modeled overtime during the connection and disconnection of linear and non-linear loads. The comparison between the probability density function (PDF) delivered by the statistical model and real data leads to the best model for the aperiodic impulsive noise. The result is the mitigation of certain frequencies by applying a filter in the noise sources that can reduce the incidence of aperiodic noise in communications. This is validated through a UDP protocol inside a Corinex PLC system in a real residential environment, expecting to see an improvement in efficiency within the communication process.
