TL;DR: This work addresses the problem of optimal antenna subset selection in spatial multiplexing systems when only the second-order statistics of the channel are available and derives selection criteria for both the maximum likelihood and zero forcing receivers, motivated by minimizing the average symbol error rate.

Abstract: Spatial multiplexing is a signaling strategy for achieving high spectral efficiencies in communication links that employ multiple transmit and multiple receive antennas. In such systems, it is desirable to use only a subset of the available transmit and/or receive antennas to reduce cost and complexity. We address the problem of optimal antenna subset selection in spatial multiplexing systems when only the second-order statistics of the channel are available. We derive selection criteria for both the maximum likelihood and zero forcing receivers, motivated by minimizing the average symbol error rate. We characterize the antenna selection gain and show that both coding gain and diversity gain is possible. We then use Monte Carlo simulations to validate our analysis.

Variable-phase-shift-based RF-baseband codesign for MIMO antenna selection
TL;DR: This work introduces a novel soft antenna selection approach for multiple antenna systems through a joint design of both RF (radio frequency) and baseband signal processing that requires only simple, variable phase shifters and combiners to reduce the number of RF chains.

TL;DR: It is shown that in ideal channels, full diversity can be achieved, and also the number of independent data streams for spatial multiplexing can be maintained if certain conditions on L are fulfilled.

Simplified Spatial Correlation Models for Clustered MIMO Channels With Different Array Configurations
TL;DR: An approximate spatial correlation model for clustered multiple-input multiple-output (MIMO) channels is proposed and used to show that the proposed model is a good fit to the existing parametric models for low angle spreads (i.e., smaller than 10deg).

Active Antenna Selection in Multiuser MIMO Communications
TL;DR: The paper develops a dynamic antenna scheduling strategy for downlink MIMO communications, where a subset of the receive antennas at certain users is selectively disabled, and shows that increasing the number of antennas at some users can degrade the SLNR performance at other users.

Fading correlation and its effect on the capacity of multielement antenna systems
TL;DR: It is shown that the fading correlation affects the MEA capacity by modifying the distributions of the gains of these subchannels, which depends on the physical parameters of MEA and the scatterer characteristics.
