ABSTRACT
This chapter addresses the statistical characterisation of multiple-input multiple-output (MIMO) signals, power line (PL) channels and noise based on experimental measurements collected in the United States. It presents a MIMO channel modelling approach based on correlation matrices. The apparatus and signalling used to characterise the MIMO PL and the transfer function of the channel is needed, as well as the noise that is present on the different receiver ports. In contrast to MIMO channel modelling on the PL, the analysis of MIMO PL noise is relatively unexplored to date. The transmitter first performs a MIMO transmission using two transmitter ports, then a single-input single-output (SISO) transmission using L-N wire pairs only and then a SISO transmission using L-PE wire pairs only. A spatial correlation between each SISO link can be introduced for each carrier based on an approach documented in several publications on MIMO channel modelling.
