摘要

本文分析了一种受背景噪声和脉冲噪声影响的窄带电力线通信系统。为了满足脉冲噪声密度函数的重尾要求，将背景噪声建模为高斯噪声，将脉冲噪声用拉普拉斯分布进行表征。此外，我们用伯努利和泊松随机变量对PLC系统中脉冲噪声的发生进行了建模。从容量的角度分析了所考虑的窄带PLC系统的性能。具体地说，导出了在伯努利-拉普拉斯和泊松-拉普拉斯脉冲噪声情况下的平均信道容量表达式。仿真结果支持了分析结果。

Capacity analysis of a NB-PLC system with background and impulsive noises

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.
