Digital compass for multi-user beam access in mmWave cellular networks
Digital Communications and Networks, 2023 Beamforming in stand-alone Millimeter-Wave (mmWave) communications results in prolonged access times and latencies due to the increased number of measurements required to determine the optimal beam directions at the Mobile Station (MS) and Base Station ...

Optical microrheology using rotating laser-trapped particles [PDF]
, 2004 We demonstrate an optical system that can apply and accurately measure the torque exerted by the trapping beam on a rotating birefringent probe particle. This allows the viscosity and surface effects within liquid media to be measured quantitatively on a

Approximations of the aggregated interference statistics for outage analysis in massive MTC [PDF]
, 2019 This paper presents several analytic closed-form approximations of the aggregated interference statistics within the framework of uplink massive machine-type-communications (mMTC), taking into account the random activity of the sensors.

A spectrum efficient cellular base-station antenna architecture [PDF]
, 1992 A concept is considered according to which using the spatial distribution of the users acquired by an array on reception, an antenna system can dynamically assign single narrow beams to illuminate lone mobiles, and broad beams to the numerous groupings ...
