Patent ID: 7778309

Claim:
A receiver of a wireless communication system, comprising: at least two receive antennas for receiving a target signal of a serving base station and interference signals of at least one neighbor base station; a channel estimator for estimating channels of the signals received through the receive antennas; and a detector for detecting the target signal using channel estimation values of the received signals, wherein the detector uses a multi-input multi-output (MIMO) signal detection scheme, and wherein when a number of the received signals is greater than a number of the receive antennas, the detector compares powers of the interference signals, selects a number from high-powered interference signals that is one less than the number of the receive antennas, and detects the target signal using the MIMO signal detection scheme, and wherein when the number of the received signals is equal to the number of the receive antennas, the detector detects the target signal using the MIMO signal detection scheme.
