Abstract
A receiver (20) for use in wireless communications with plural transmitters (22) comprises transmitter selection logic (34); a signal estimator (36); and an image estimator (38). The image estimator (38) is configured to form an estimate of an image signal occurring on the second sub-carrier and attributable to a transmission of the first transmitter. The signal estimator (36) is configured, e.g., to use the estimate of the image signal and a signal received on the second sub-carrier to obtain an estimate of a portion of the signal received on the second sub-carrier which is attributable to the second transmitter. Thus, the receiver (20) is able to determine the portion of the signal received on the second sub-carrier which is attributable to the second transmitter in a way that compensates for the image signal occurring at the second sub-carrier.
