Patent ID: 8077646

Claim:
A method of equalization within a communication system having i) a first transceiver device and ii) a plurality of second transceiver devices, wherein the first transceiver device communicates with each of the second transceiver devices via a subset of frequency sub-carriers allotted to each second transceiver device, the method comprising: receiving a data transmission over the subset of frequency sub-carriers, wherein 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; transforming the data transmission from a time-domain transmission to a frequency domain transmission; selecting one or more of the frequency sub-carriers within the subset of frequency sub-carriers; and applying a separate equalization filter to each of the frequency sub-carriers within the subset of frequency sub-carriers, wherein the equalization filter applied separately to each of the selected frequency sub-carriers comprises a multi-coefficient equalization filter, and wherein the equalization filter for each of unselected frequency sub-carriers comprises a single-coefficient equalization filter.
