FIELD: radio engineering.
SUBSTANCE: invention relates to the field of radio engineering; it can be used in a multiuser radio communication system with multiple input and multiple output (hereinafter – MIMO) antennas and precoding with a reverse channel. A sequence of interconnected actions is used, including a procedure of different orthogonal conversions of a channel vector of MIMO channel, previous to a quantization procedure by method for selection of a code word at subscriber stations, filtration of restored assessments of channel vectors at a base station, and selection of served subscriber stations, taking into account the accuracy of filtered assessments. The use of the method is effective in systems with a large number of antennas at the base station.
EFFECT: increase in the bandwidth and capacity of a multiuser communication system with MIMO channel.
