1. A method comprising:
in a training phase:
transmitting, from a transmitter node via a first channel, a first known training signal to a first receiver node for receipt as a first distorted training signal,
based on the first distorted training signal and the first known training signal, determining, by the transmitter node, a first transmit-side equalizer (EQ) coefficient associated with the first channel,
transmitting, from the transmitter node via a second channel, a second known training signal to a second receiver node for receipt as a second distorted training signal, and
based on the second distorted training signal and the second known training signal, determining, by the transmitter node, a second transmit-side EQ coefficient associated with the second channel; and
in a communication phase:
identifying, by the transmitter node, time intervals during which one of the first channel and the second channel will be activated; and
equalizing, by the transmitter node using the first transmit-side EQ coefficient or the second transmit-side EQ coefficient, signals prior to transmission in the time intervals during which the one of the first and second channels will be activated.
