Capacity limits of MIMO channels
TL;DR: An overview of the extensive results on the Shannon capacity of single-user and multiuser multiple-input multiple-output (MIMO) channels is provided and it is shown that the capacity region of the MIMO multiple access and the largest known achievable rate region (called the dirty-paper region) for the M IMO broadcast channel are intimately related via a duality transformation.
Journal ArticleDOI
Duality, achievable rates, and sum-rate capacity of Gaussian MIMO broadcast channels
TL;DR: It is shown that the dirty paper achievable region achieves the sum-rate capacity of the MIMO BC by establishing that the maximum sum rate of this region equals an upper bound on the sum rate.
Journal ArticleDOI
MIMO Broadcast Channels With Finite-Rate Feedback
TL;DR: A key finding is that the feedback rate per mobile must be increased linearly with the signal-to-noise ratio (SNR) (in decibels) in order to achieve the full multiplexing gain.
Journal ArticleDOI
Multi-Antenna Downlink Channels with Limited Feedback and User Selection
TL;DR: This work analyzes 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, and shows that having more users reduces feedback load.
Proceedings ArticleDOI
MIMO broadcast channels with finite rate feedback
TL;DR: A system where the receiver has perfect channel knowledge, but the transmitter only receives quantized information regarding the channel instantiation is analyzed and simple expressions for the capacity degradation due to finite rate feedback as well as the required increases in feedback load per mobile as a function of the number of access point antennas and the system SNR are provided.
