Title: ENHANCED MULTI-USER MIMO DETECTION
Abstract:
Apparatuses and methods are disclosed for receiving or obtaining wireless signals. A first wireless device may receive a wireless signal including a first signal and a number of second signals. The first signal may contain data intended for the first wireless device, and the number of second signals may contain data intended for one or more second wireless devices. The first wireless device may select one or more of the number of second signals, determine a pre-whitening matrix based on an interference and noise covariance of the unselected second signals, and recover the first signal by using the pre-whitened signal.
