Methods and apparatuses for versatile beamforming

Paul Hurley, Matthieu Martin Jean-André Simeoni

The present invention is directed to methods and apparatuses for beamforming signals or compute beamformed signals. The present approach is to determine a series of beams from or for a set of devices configured for receiving signals from and/or transmittin ...

Spatial Multiplexing of QPSK Signals With a Single Radio: Antenna Design and Over-the-Air Experiments

Juan Ramon Mosig, Andreas Peter Burg, Julien Perruisseau-Carrier, Mohsen Yousefbeiki, Andrew Charles Mallory Austin

This paper describes the implementation and performance analysis of the first fully operational beam-space multiple-input multiple-output (MIMO) antenna for the spatial multiplexing of two QPSK streams. The antenna is composed of a planar three-port radiat ...

Apodization Scheme for Hardware-Efficient Beamformer

Jean-Philippe Thiran, Giovanni De Micheli, Federico Angiolini, Aya Mohamed Naguib Ahmed Ibrahim, Marcel Arditi

3D ultrasound is an emerging diagnostic technique that extends standard ultrasound imaging by capturing volumes, instead of planes. This brings completely new diagnostic opportunities, among which the possibility of disjoining image acquisition and analysi ...
