Patent ID: 7623602

Claim:
An interference canceller coupled to a plurality of receive antennas configured for receiving signals from a plurality of transmit antennas in a system wherein closed loop transmit waveform shaping is employed, the interference canceller comprising: a front-end module configured for determining a set of dominant beamforming weights for transmit antennas of each of a plurality of transmit sources; the front-end module comprising, a combiner configured for combining signals from the plurality of receive antennas for each of the plurality of transmit sources for producing a plurality of combined signals, a despreading module configured for employing the set of dominant beamforming weights and resolving the plurality of combined signals onto a signal basis for the plurality of transmit sources to produce soft symbol estimates, and a mixed-decision module configured for performing a mixed decision on each of the soft symbol estimates to produce initial symbol decisions.
