Аннотация
A new method for correcting the Massive MIMO system for MRT precoding in a downlink channel in order to recover the reciprocity of the channel is considered. It is shown that the lack of reciprocity of the channel between the base station and the user equipment is the main factor deteriorating the system performance. It is also established that the correction is necessary only for the equipment of the base station in the downlink. An estimate of the quality of the algorithm is given.
