Physical-Layer Multicasting by Stochastic Transmit Beamforming and Alamouti Space-Time Coding
Physical-Layer Multicasting by Stochastic Transmit Beamforming and Alamouti Space-Time Coding
Consider transceiver designs in a multiuser multi-input single-output (MISO) downlink channel, where the users are to receive the same data stream simultaneously. This problem, known as physical-layer multicasting, has drawn much interest. Presently, a popularized approach is transmit beamforming, in which the beamforming optimization is handled by a rank-one approximation …
