Multiple Input Multiple Output Signals on
"... Abstract—In this paper, we propose a novel ML decoding scheme based on the combination of depth- and breadth-first search methods on a partitioned tree for multiple input multiple output (MIMO) systems. The proposed scheme first partitions the searching tree into several stages, each of which is the ..."

The interest in Multiple Input Multiple Output
"... 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
- 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
- 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
, 2007
"... We derive a criterion on the measurability / identifiability of Multiple–Input Multiple–Output (MIMO) channels based on the size of the so-called spreading support of its subchannels. Novel MIMO transmission techniques provide high-capacity communication channels in time-varying environments and exa ..."
