METHOD AND SYSTEM FOR ORTHOGONALIZED BEAMFORMING IN MULTIPLE USER MULTIPLE INPUT MULTIPLE OUTPUT (MU-MIMO) COMMUNICATION SYSTEMS

摘要

A method and system for orthogonalized beamforming in multiple user multiple input multiple output (MU-MIMO) communication systems are presented. Aspects of the method and system include an iterative method for computing a plurality of beamforming matrices in a MU-MIMO system. A transmitting station, such as an access point (AP) for example, may use computed channel estimates, and/or singular vector matrices, to compute orthogonal beamforming matrices. The computed orthogonal beamforming matrices may be used to generate a plurality of signals, which may be concurrently transmitted to the plurality of user devices.
