A multi-threshold scheme for feedback load reduction in multiuser MIMO broadcast channel
In a multiuser system, independent time-varying channels among different users can be exploited to provide multiuser diversity (MUD) gain and increase the system throughput. For th...

Ergodic and Outage Performance of Fading Broadcast Channels with 1-Bit Feedback
In this paper, the ergodic sum-rate and outage probability of a downlink single-antenna channel with K users are analyzed in the presence of Rayleigh flat fading, where limited cha...

Feedback reduction in MIMO broadcast channels with LMMSE receivers
In this paper we analyze the performance of random beamforming schemes in a multi-user Gaussian broadcast channel. Each user will have N > 1 receive antennas allowing optimal c...

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...
