Abstract
A base station device, method, and communication system are disclosed. The base station includes a covariance matrix obtaining unit forming a covariance matrix of an interference vector and a noise vector from received signals from multiple user equipment; a ratio calculation and comparison unit that calculates a relative ratio between the interference and the noise in the received signals based on the covariance matrix and compares the ratio with a predetermined threshold; an adjusting unit that reduces values of non-diagonal elements in the covariance matrix when the ratio is less than the predetermined threshold; an equalizer unit that performs equalization based on the covariance matrix using an Interference Rejection Combining algorithm when the ratio is greater than or equal to the predetermined threshold, and equalizes the received signals based on the adjusted covariance matrix using a Minimum Mean Square Error algorithm when the ratio is less than the predetermined threshold.
