Exploiting Known Interference as Green Signal Power for Downlink Beamforming Optimization
Exploiting Known Interference as Green Signal Power for Downlink Beamforming Optimization
We propose a data-aided transmit beamforming scheme for the multi-user multiple-input-single-output (MISO) downlink channel. While conventional beamforming schemes aim at the minimization of the transmit power subject to suppressing interference to guarantee quality of service (QoS) constraints, here we use the knowledge of both data and channel state information (CSI) …
