To obtain the full variability of the PLC channel, random channel generators are of great importance for the design and testing of communication algorithms. In this respect, we propose a random channel generator that is based on the top-down approach. Basically, we describe the multipath propagation and the coupling effects with an analytical model. We introduce the variability into a restricted set of parameters and, finally, we fit the model to a set of measured channels. The proposed model enables a closed-form description of both the mean path-loss profile and the statistical correlation function of the channel frequency response. As an example of application, we apply the procedure to a set of in-home measured channels in the band 2-100 MHz whose statistics are available in the literature. The measured channels are divided into nine classes according to their channel capacity. We provide the parameters for the random generation of channels for all nine classes, and we show that the results are consistent with the experimental ones. Finally, we merge the classes to capture the entire heterogeneity of in-home PLC channels. In detail, we introduce the class occurrence probability, and we present a random channel generator that targets the ensemble of all nine classes. The statistics of the composite set of channels are also studied, and they are compared to the results of experimental measurement campaigns in the literature. date: 2012-07 date_type: published publisher: IEEE official_url: http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6216470 id_number: 10.1109/TPWRD.2012.2196714 full_text_status: public publication: IEEE Transactions on Power Delivery volume: 27 number: 3 pagerange: 1477-1484 institution: Telecomunicacion department: Senales refereed: TRUE issn: 0885-8977 rights: by-nc-nd citation: Tonello, Andrea and Versolatto, Fabio and Béjar Haro, Benjamín and Zazo Bello, Santiago (2012).
