A robust superimposed training sequence design is proposed for spatially correlated multiple-input-multiple-output (MIMO) channel estimation. The proposed scheme does not require accurate knowledge of the spatial correlation matrix, and it is shown to outperform previously proposed robust correlated MIMO channel estimators, such as relaxed minimum mean square error (RMMSE) and least-square RMMSE. ...

While vehicular congestion is very often defined in terms of aggregate parameters, such as traffic volume and lane occupancies, based on recent findings, the interpretation that receives most credit is that of a state of a road where traversing vehicles experience a delay exceeding the maximum value typically incurred under light or free-flow traffic conditions. We here propose a new definition ac... View full abstract»

Vibration and noise are common problems in engine-based designs such as generators used in recreational vehicles (RVs). In variable-speed applications, at lower loads, the engine can be run at slower speeds to reduce noise. However, one of the main problems incurred from running an engine at a lower speed is that the vibration modes will shift to lower frequencies, where the mounting system may no...
