Abstract  Abstract

FIELD: radio engineering communication.SUBSTANCE: invention relates to communication engineering and can be used in MIMO systems. The invention discloses a method (700 900) and a transceiver (10 12) which employ a factored precoder structure. A full precoder (36) is formed from a conversion precoder (32) and a setup precoder (34). There are 2Nconversion precoders (32) each comprising a block-diagonal matrix having two or more columns with blocks on the matrix diagonal wherein each block comprises a precoder (38) of DFT-based antenna subgroup which corresponds to a subgroup from Ntransmitting antenna ports (98) in a transceiver (10) and provides 2Ndifferent DFT-based beams for the corresponding subgroup and wherein all of the 2Ndifferent conversion precoders (32) are reusable along with one or more setup precoders (34) for creating a set of 2Ndifferent full precoders (36) wherein each full precoder (36) is a DFT-based beam measuring Nby Ntransmitting antenna ports (98).EFFECT: high communication reliability.19 cl 11 dwg
