Abstract
Provided are a base station apparatus, a terminal apparatus, a wireless communication system, and an integrated circuit in which the terminal apparatus is able to appropriately combine signals received by a plurality of receive antennas in the wireless communication system for performing nonlinear MU-MIMO transmission. The base station apparatus of the invention has a plurality of antennas, is able to apply nonlinear precoding to data signals addressed to a plurality of terminal apparatuses, and spatially multiplexes and transmit the data signals, and based on the data signals and channel information between the base station apparatus and the terminal apparatuses, searches for a perturbation vector to be added to the data signals, and further calculates a covariance matrix of the signals obtained by adding the perturbation vector to the data signals. The terminal apparatus of the invention detects a desired signal from among the signals transmitted from the base station apparatus, based on the covariance matrix.
