MULTI-USER MULTIPLE FLOW ITERATIVE DUAL TRANSMISSION METHOD FOR MULTI-USER MIMO SYSTEM, TRANSMITTER, COMPUTER PROGRAM PRODUCT AND CORRESPONDING INFORMATION MEDIUM

摘要

The present invention relates to a multi-stream transmission method (0) of N data streams allocated to K different users, implemented by a transmitter intended for a multi-user MIMO system with N transmit antennas and associated reception antennas. to K receivers respectively associated with K users. The method comprises: - the succession of two different iterative algorithms (0.1, 0.2) for calculating K precoding matrices of a linear precoder and K decoding matrices of a receiver, this receiver being of MF type standardized with a standard of Frobenius for the first algorithm, the second iterative algorithm being initialized by an output value of the first iterative algorithm, - before each calculation of the precoding matrices, a calculation of weight to weight all the flows.
