On the outage and diversity-multiplexing tradeoff of broadcast channels with 1-bit feedback
In this paper, a single antenna downlink channel with K users is analyzed in the presence of Rayleigh flat fading. A limited channel state information (CSI) feedback scheme is co...

Coordinated beamforming with limited feedback in the MIMO broadcast channel
In this paper, we propose a new joint optimization of linear transmit beamforming and receive combining vectors for the multiple-input multiple-output (MIMO) broadcast channel. We ...
