ISI and ICI Suppression for Mobile OFDM System by Using a Hybrid 2-Layer Diversity Receiver
An OFDM system is very sensitive to orthogonality relation. For a mobile wireless system, it is impossible to avoid Doppler-induced inter carrier interference (ICI). Moreover, whil...

A sensor-based approach to linear blur identification for real-time video enhancement
Super-resolution (SR) methods are largely affected by the accurate evaluation of the Point Spread Function (PSF) that is related to the input frames. When the frames are degraded ...
