The interest in Multiple Input Multiple Output

by Qi Zhan, Guangxi Zhu, Li Tan, Peng Shang, Gang Su, Abstract—the Combined Block Diagonalization
"... Geometric Mean Decomposition (BD-GMD) is a precoding scheme that is asymptotically optimal for downlink Multi-User Multiple-Input-Multiple-Output(MU-MIMO)systems. BD-GMD eliminate the interference between different user channels in MU-MIMO system under ideal condition, which leads to an improvement ..."

Polarization characteristics of multiple-input multiple-output channels

by Lei Jiang, Lars Thiele, Armin Brylka, Stephan Jaeckel, Volker Jungnickel - in Proc. PIMRC’08 , 2008
"... Abstract-In this paper, we investigate the polarization charac-teristics of the multiple-input multiple-output (MIMO) channels. The cross polarization discrimination (XPD) is found to change over time, while its variation in frequency domain is relatively small. The probability density function (PDF ..."

Ultra wideband multiple-input multiple-output radar

by Hammad A. Khan, Wasim Q. Malik, David J. Edwards, Christopher J. Stevens - in Radar Conference, 2005 IEEE International , 2005
"... The utilization of ultra wideband (UWB) signals enables the radar designer to solve the most important problems of radar target observation. The extremely wide bandwidth enables greater information to be obtained due to high time resolution and the frequency dependence of the scattering centers over ..."

Measurement of time–varying Multiple–Input Multiple–Output Channels

by G. E. Pfander , 2007

The capacity region of the Gaussian multiple-input multiple-output broadcast channel

by Hanan Weingarten, Yossef Steinberg, Shlomo Shamai (Shitz) - IEEE TRANS. INF. THEORY , 2006
"... The Gaussian multiple-input multiple-output (MIMO) broadcast channel (BC) is considered. The dirty-paper coding (DPC) rate region is shown to coincide with the capacity region. To that end, a new notion of an enhanced broadcast channel is introduced and is used jointly with the entropy power inequa ..."
