FIELD: information technologies.
SUBSTANCE: feedback information is received from a mobile station (MS), channel coding is carried out, as well as modulation of user data, using the received feedback information, preliminary coding matrix is identified based on the phase shift with application of preliminary coding matrix, selected from a code book on the basis of space multiplexing ratio, besides, the code book includes the first matrix of preliminary coding with a relatively low ratio of space multiplexing and the second matrix of preliminary coding with a relatively higher ratio of space multiplexing, preliminary coding of user data is carried out in the pre-coder, and output signals are sent to a mobile station.
EFFECT: reduction or minimisation of noise between users.
