Multiple-Antenna Multicasting Using Channel Orthogonalization and Local Refinement

The problem of single-group multiple-antenna multicasting is considered, where common information should be sent to a large number of users. The multiple-antenna transmitter is assumed to accurately know the instantaneous downlink channel state information (CSI) for all users, and our objective is t...
