A METHOD FOR MULTI-USER SIGNAL TRANSMISSION IN MASSIVE ANTENNA-BASED WIRELESS COMMUNICATION SYSTEMS

摘要

The present invention relates to a method for simultaneously transmitting multiple signals in a multi-user wireless communication system using a large-scale multi-antenna. A multi-signal transmission method such as the prior zeroforcing beamforming (ZFBF) whereby signals of multiple users are transmitted at the same time by using a large-scale antenna requires highly complicated calculation and thus cannot implemented in an easy manner. The method of the present invention can significantly reduce complexity of implementing a multi-signal transmission method using a large-scale antenna while deterioration of performance of the method is less than that of the prior method as interference between beams of multiple users are sequentially eliminated.
