16.1  Introduction

Multiple-input multiple-output (MIMO) technology enhances the performance of PLC systems by utilising multiple ports for sending and receiving signals (see Chapters 8, 9, 12, 14 and 24). Beamforming or precoding is used in several current power line communication (PLC) systems (see Chapters 12 and 14) and significantly improves their performance ...
