An experimental evaluation of three candidate MIMO array designs for PDA devices

, 2004
It is well known that multiple-input, multiple-output (MIMO) wireless channels, in which multi-element antenna arrays are used at both ends of the link, can in principle offer spectral efficiencies an order of magnitude or more above those available ...

A universal space-time architecture for multiple-antenna aided systems

, 2012
In this tutorial, we first review the family of conventional multiple-antenna techniques, and then we provide a general overview of the recent concept of the powerful Multiple-Input Multiple-Output (MIMO) family based on a universal Space-Time Shift ...

Adaptive Multi-Node Multiple Input and Multiple Output (MIMO) Transmission for Mobile Wireless Multimedia Sensor Networks

Sensors, 2013
Mobile wireless multimedia sensor networks (WMSNs), which consist of mobile sink or sensor nodes and use rich sensing information, require much faster and more reliable wireless links than static wireless sensor networks (WSNs).

A spatial interference minimization strategy for the correlated LTE downlink channel [PDF]

, 2010
In a downlink transmission, users can benefit from the high capacity gain achieved by transmitting independent data streams from multiple antennas to multiple users sharing the same physical time-frequency resources.
