Aiming perfectly in the dark-blind interference alignment through staggered antenna switching
FREE-DOWNLOAD C Wang, T Gou… 2010 – We propose a blind interference alignment scheme for the vector broadcast channel where the transmitter is equipped with M antennas and there are K receivers, each equipped with a reconfigurable antenna capable of switching among M preset modes. Without any knowledge of the
Surface plasma on resonances of optical antenna atomic force microscope tips
FREE-DOWNLOAD Y Zou, P Steinvurzel, T Yang… – Applied Physics Letters, 2009 Scanning near field optical microscopy enables optical imaging on a subwavelength scale below the resolution limit of far field optics. The spatial resolution and signal-to-noise ratio in scattering and tip enhanced optical near field imaging depend on the degree to which the .
new reconfigurable antenna design for cognitive radio
FREE-DOWNLOADgY Tawk… – Antennas and Wireless …, 2009 Abstract—This letter presents a new antenna design suitable for cognitive radio communication. It consists of two structures incorporated together into the same substrate. The first structure is an ultrawideband (UWB) antenna covering the spectrum from 3.1–11 GHz
