ABSTRACT:
An equalization method and apparatus for a communication system having a first transceiver device that communicates with each of a plurality of second transceiver devices receives a data transmission over a subset of frequency sub-carriers allotted to each second transceiver device. The communication channel between first transceiver device and the plurality of second transceiver devices is partitioned in a plurality of frequency sub-carriers of which the frequency sub-carriers allotted to a second transceiver device is a subset. The data transmission is transformed from a time-domain transmission to a frequency domain transmission. An equalization filter is applied separately to each of the frequency sub-carriers within the subset of frequency sub-carriers.
