Patent ID: 7385944

Claim:
A method of canceling interference in transmissions from a group of users in a communication system, comprising: selecting a known highest data rate user transmission of the group from a received first signal containing the group's transmissions, the highest rate user transmission representing a second signal configured as one or more received frames, each frame including a control preamble and a plurality of encoded sub-frames; first decoding the control preamble in a first timeslot to determine a channel phase and gain estimate for a first one of the plurality of encoded sub-frames; and second decoding the first encoded sub-frame in a next timeslot using the determined channel phase and gain estimate to provide a revised channel phase and gain estimate, the second decoding repeated for remaining encoded sub-frames using determined channel phase and gain estimates from all previously decoded sub-frames; and removing interference due to the highest rate user transmission from the first signal using the decoded sub-frames.
