    Patent number: 7680199
    Abstract: In a multi user communication system, subcarriers are allocated to subchannels using a quality measurement for each subchannel. An initial sub carrier is allocated to each subchannel, and a quality metric measured. Subsequent subcarriers are allocated in dependence upon the quality measurement for each subchannel. The subchannel with the lowest quality measurement receives the first allocation, and the subchannel with the highest quality measurement receives the last allocation. The subsequent allocation is repeated, following a re-sort of the subchannel quality measurements, until all of the subcarriers are allocated.
