Multiple-input multiple output (MIMO) systems are able to serve multiple users simultaneously and using the same frequency band. Therefore, they have a quite crucial position in the design of 5G and future communication systems. However, as the number of users to be served increases, they may fail to suppress the inter-user interference adequately. It has been shown in literature that increasing the number of receive antennas is a solution to cope with severe inter-user interference distortion. Therefore, MIMO systems consisting of a vast number of received antennas, namely massive MIMO systems, are among the candidate schemes to be used in future communication standards. In this study, a new technique based on the time of the samples taken at the receiver side is proposed. With the proposed method, better performance is obtained in terms of the error vector magnitudes of the received symbols.
