A Capacity Mode Assessment and Interference Suppression in MU-MIMO Systems

Growing communication quality and data transmission technologies needs for applying more and more antennas are required, which are an integral part of the multi-user Multiple Input Multiple Output (MU-MIMO) wireless communications system. The MIMO topic, in a broad sense, includes special transmission methods, which can be divided into two main subgroups: spatial diversity, the main task of which is error-correcting data coding, that is, increasing transmission noise immunity and the second one, what we were focused on is spatial multiplexing, which is directly related to channel capacity. In this paper, were considered the particular problems such as increasing capacity, maximizing the full information transfer rate in the channel, taking into account the need to optimize the output power in proportion to the propagation path and interference suppression.
