The aim of this paper is to study the problem of load- time variation in power line communication (PLC) systems and to analyze asynchronous impulsive noise and related channel varia- tions due to switch commutations.

Abstract

The aim of this paper is to study the problem of load- time variation in power line communication (PLC) systems and to analyze asynchronous impulsive noise and related channel varia- tions due to switch commutations. A numerical model of the time- varying communication channel is developed by using scattering parameters in the wavelet domain. The proposed method uses the N-port description of the elements that constitute a time-varying PLC system in terms of real matrices with constant elements. This represents a valid alternative to the time domain description usu- ally adopted for analyzing time-varying networks. The comparison with results obtained from other numerical models and with exper- imental data has confirmed the accuracy and the efficiency of the proposed method.
