Feedback in a communications system can enable the transmitter to exploit channel
conditions and avoid interference. In the case of a multiple-input multiple-output channel …

Explores the fundamentals required to understand, analyze, and implement space
modulation techniques (SMTs) in coherent and non-coherent radio frequency environments …

Currently, space division multiplexing (SDM), where individual data streams are transmitted
from different antennas simultaneously, is expected to be a promising technology for …

This letter reports the experimental demonstration of an indoor visible light nonimaging
multiple-input multiple-output system with an aggregate error free bit rate of 50 Mb/s over a …

Spatial multiplexing is a simple transmission technique for multiple-input multiple-output

A random beamforming technique for multiple-input multiple-output (MIMO) systems that
simultaneously obtains downlink multiuser diversity gain, spatial multiplexing gain and array …

This work considers the combined design of bit loading, precoding and receives filters for a
multiple-input-multipleoutput (MIMO) digital communication system. Both the transmitter and …

We consider spatial multiplexing systems in correlated multiple-input multiple-output (MIMO)
