A study of asynchronous noise in indoor power line with applications to power line communication

Abstract

Power line channels do not have standard models for noise simulation. As such, study and analysis of different types of noise is imperative to developing channel simulator where communication systems can be tested and optimized for maximum efficiency. This is an indispensable part in developing power line communication systems that uses the available power line as a communication channel. This paper analyzes the asynchronous impulsive noise in indoor power line channels. The experimental setup for noise acquisition is described in detail. It is found that the impulse amplitude and the impulse durations follow the t-location scale and the log-logistic distribution better than other distribution tested. Such a distribution is easier to handle in terms of random number generation using the inverse cumulative distribution method. This can be used in the random noise simulation of impulsive noise in the generation of overall power line noise for system testing and optimization.
