Multiple input, multiple output (MIMO) communication system over in-premises wires

A multiple input, multiple output (MIMO) communications unit includes a multiplicity of analog front ends and a MIMO processor. Each analog front end is connectable to a different two of the wires in a subscriber premises and each handles data of one channel. The MIMO processor processes together the data of the channels. In one embodiment, the wires are the power line wires in a subscriber premises, including the phase, neutral and ground power line wires. In another embodiment, the wires are pairs of telephony wires.
