Combining techniques performance analysis in spatially correlated MIMO-PLC systems

A brief introduction to MIMO-PLC as well as the special case of SIMO-PLC is provided. It is shown that in MIMO-PLC channels, a spatial correlation is inevitable and channels are not spatially independent. A physical as well as a mathematical description of the spatial correlation in MIMO-PLC is provided. Furthermore, two reception diversity techniques, Maximum Ratio Combining (MRC) and Equal Gain Combining (EGC) are studied and numerical results are presented.
