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 ...

Optimizing Quantize-Map-and-Forward in Slow Fading Relay Networks

Christina Fragouli, Ayan Sengupta, I-Hsiang Wang

Quantize-Map-and-Forward (QMF) relaying has been shown to achieve the optimal diversity-multiplexing trade-off (DMT) for the slow fading single-antenna relay channel, regardless of whether the relay is full-duplex or half-duplex. A key reason for the DMT o ...

Coded SC-FDMA for broadband satellite return links

Stefano Rosati

In this paper we deal with Single Carrier Frequency Division Multiple Access (SC-FDMA) as uplink air interface of broadband satellite networks. Interestingly, SC-FDMA enables a significant increase of the spectral efficiency with respect to the state-of-th ...

Fatigue analysis of liquid-storage tank shell-to-base connections under multi-axial loading

Alain Nussbaumer, Gary Scott Prinz

During severe seismic events the base of unanchored steel liquid-storage tanks can uplift, causing large inelastic rotation demands at the shell-to-base connections and large multi-axial stresses (radial tension and circumferential compression) in the tank ...

A New Planar Antenna Element For Ka-Band Applications

Juan Ramon Mosig, Jean-François Zürcher, Rafal Glogowski

One of the most promising bands for long-range radiocommunications is the Ka-band (25-40 GHz). This is due to the existence of a natural radio transmission window around 30 GHz. Both terrestrial and satellite transmission systems are planned on this freque ...
