Résumé

The Multiple-Input Multiple-Output (MIMO) technique is well known in the field of wireless communications, and has recently been proposed to increase the capacity of in-home Power Line Communication (PLC) networks. MIMO PLC employs the Protective Earth in addition to the classical Line and Neutral wires, to form a multi-sensor transmission channel. By considering the additional reception of Common Mode signals, up to 2 simultaneous transmit ports and 4 receive ports can be considered. In order to develop new signal processing strategies optimally exploiting the MIMO propagation characteristics, and to evaluate their performance, accurate modeling of the transmission channel is necessary. This paper presents a comprehensive statistical model of the in-home MIMO PLC channel based on an extensive measurement data base collected in 6 European countries. The study first analyses the main MIMO PLC channel parameters, including path loss parameters and wideband parameters such as the delay spread, coherence bandwidth and small-scale statistics. A focus is then made on the MIMO correlation matrix, and its modelling using empirical statistical distributions. A fully parameterized channel model is then developed, with a particular emphasis on both the frequency fading structure of the transfer function and the correlation matrix between sub-channels. As a result, the proposed model generates random MIMO PLC channel realizations statistically representative of the experimental observations.
