Experimental and analytical evaluation of multi-user beamforming in wireless LANs
Adaptive beamforming is a. powerful approach to receive or transmit signals of interest in a spatially selective way in the presence of interference and noise. Recently, there has been renewed interest in adaptive beamforming ...
Non-invasive IC tomography using spatial correlations
We introduce a new methodology for post-silicon characterization of the gate-level variations in a manufactured Integrated Circuit (IC). The estimated characteristics are based on the power and the delay measurements that ...
Resistive switching in silicon oxide-based systems
Voltage-controlled resistive switching in various gap systems on SiO2 substrates is demonstrated. The nanosized gaps are made by several means using different materials including metals, semiconductors and amorphous carbon. ...
BeamSwitch: System solution for energy-efficient directional communication on mobile devices
Directional communication has the potential to improve both the energy efficiency of wireless communication without sacrificing its quality. We present a system solution, BeamSwitch, for directional communication on mobile ...
A hybrid relaying protocol for the parallel-relay network
Cooperation among radios in wireless networks has been shown to improve communication in several aspects. We analyze a wireless network which employs multiple parallel relay transceivers to assist in communication between ...
The transition from a TEM-like mode to a plasmonic mode in finite-width THz parallel-plate waveguides
By the near-field measurement of the electric field distribution inside the finite width THz parallel plate waveguide, we find the transition from conventional diffractive TEM-like mode to plasmonic mode. This mode transition ...
