Abstract
A method of communicating across power lines, including communicating data between at least two in-premises network devices along more than one channel, each channel defined by a different two of a plurality of wires in a subscriber premises, a first channel forming a straight path channel and a second channel forming a cross-path channel, and using multiple-input, multiple-output (MIMO) processing and maximum ratio combining (MRC) processing of data received along the plurality of wires, at least a portion of the data being received simultaneously from the straight path channel and the cross-path channel, wherein the wires are phase, neutral and ground wires of a subscriber premises.

A multiple-input, multiple-output (MIMO) communications receiver for an in-premises multi-point network, the receiver comprising:
- a multiplicity of analog front ends each connectable to a different two of a plurality of wires in a subscriber premises, said plurality of wires forming a shared medium of said network, and each said analog front end to receive data of one channel;
- and
- a MIMO processor to process together data received from said channels, at least a portion of said data being received simultaneously from said channels,
- wherein said multiplicity is at least two,
- wherein said wires are phase, neutral and ground power line wires of said premises,
- wherein one analog front end is connectable to said phase and neutral wires, thereby forming a first channel and another analog front end is connectable to said neutral and ground wires, thereby forming a second channel,
- wherein one of said first channel and said second channel is a straight path channel and wherein the other one of said first channel and said second channel is a cross-path channel, and
- wherein said MIMO processor uses maximum ratio combining (MRC) to process said data received from said straight path channel and said cross-path channel.
