Abstract

See full text

A method implemented in a network element (NE), comprising obtaining, via a processor of the NE, a plurality of encoded signals associated with a plurality of downstream (DS) channels in a network, wherein the plurality of DS channels form a plurality of DS multiple-input and multiple-output (MIMO) groups, performing, via the processor, MIMO pre-coding on the plurality of encoded signals according to the plurality of DS MIMO groups, performing, via the processor, crosstalk pre-coding on the plurality of encoded signals jointly after performing the MIMO pre-coding to produce a plurality of output signals, and transmitting, via transmitters of the NE, synchronously the plurality of output signals to a plurality of remote NEs via the plurality of DS channels.
