MIMO broadcast channels with finite rate feedback
TLDR
Multiple transmit antennas in a downlink channel can provide tremendous capacity (i.e. multiplexing) gains, even when receivers have only single antennas. Expand

Duality, achievable rates, and sum-rate capacity of Gaussian MIMO broadcast channels
TLDR
We consider a multiuser multiple-input multiple- output (MIMO) Gaussian broadcast channel (BC), where the transmitter and receivers have multiple antennas. Expand

Multi-Antenna Downlink Channels with Limited Feedback and User Selection
TLDR
We analyze the sum-rate performance of a multi- antenna downlink system carrying more users than transmit antennas, with partial channel knowledge at the transmitter due to finite rate feedback. Expand

Sum power iterative water-filling for multi-antenna Gaussian broadcast channels
TLDR
We use a "duality" to transform this problem into a convex multiple access problem, and then obtain a simple and fast iterative algorithm that gives us the optimum transmission policies. Expand

Multiuser MIMO Achievable Rates With Downlink Training and Channel State Feedback
TLDR
In this paper, we consider a multiple-input-multiple-output (MIMO) fading broadcast channel and compute achievable ergodic rates when channel state information is acquired at the receivers via downlink training and it is provided to the transmitter by channel state feedback. Expand

  • 20 November 2007
TLDR
Block diagonalization is a linear preceding technique for the multiple antenna broadcast (downlink) channel that involves transmission of multiple data streams to each receiver such that no multi-user interference is experienced at any of the receivers. Expand
