Abstract

In this paper, we analyze a narrowband power line communication (PLC) system under the influence of additive background and impulsive noises. The background noise is modeled as the Gaussian noise, whereas, the impulsive noise is characterized by the Laplace distribution, in order to satisfy the heavy tail requirement of the impulsive noise density function. Moreover, we model the occurrence of impulsive noise in PLC system with Bernoulli and Poisson random variables. We analyze the performance of considered narrowband PLC system in terms of capacity. Specifically, expressions for average channel capacity are derived in case of Bernoulli-Laplace and Poisson-Laplace impulsive noises. The analytical results are supported by the simulations.
