Abstract
In this paper, we consider a transmit antenna and user selection for maximumlikelihood (ML) detector in multiuser spatial multiplexing systems. The conventional algorithm thatmaximizes theminimum streamSNRis not optimal in terms of the error probability, because it is tailored for linear detectors.We propose a simple transmit antenna and user selection scheme for the ML detector based on maximizing the minimum distance. Numerical results show that the proposed scheme provides enhanced performance compared with the conventional algorithms in terms of the error probability of ML receiver.
