Normalized GNSS Interference Pattern Technique

Pierre-André Farine, Cyril Botteron, Jérôme Leclère, Miguel Angel Ribot Sanfelix, Mohammed Benjelloun

It is well known that water level and snow height can be monitored with the ground reflectometry GNSS-R approach [1, 2]. In this approach the antenna situated on a mast, receives a direct GNSS signal coming from the satellite and a nadir signal reflected b ...

Ab initio reconstruction of difference densities by charge flipping

Thomas Alois Weber, Philip Pattison

The charge-flipping algorithm in its band-flipping variant is capable of ab initio reconstructions of scattering densities with positive and negative values. It is shown that the method can be applied to reconstructions of difference electron densities of ...

Multiuser Two-Way Amplify-and-Forward Relay Processing and Power Control Methods for Beamforming Systems

Ali H. Sayed

In this paper, multiple-input multiple-output (MIMO) relay transceiver processing is proposed for multiuser two-way relay communications. The relay processing is optimized based on both zero-forcing (ZF) and minimum mean-square-error (MMSE) criteria under ...
