A PLC broadband channel simulator for indoor communications

In this paper we propose a frequency-domain broadband channel simulator for indoor power line communications (PLC). We follow a bottom-up approach by defining the topology in a fixed mode or in a random mode. The channel matrix coefficients are derived by using the well-known two-port ABCD line modeling. The channel simulator takes into account cable characteristics, effective lengths of branches, and also loads by selecting the load impedances from a predefined set. We will show how to use our bottom-up channel simulator to generate random PLC channels and to match measurement results with a predefined approximation.
