Radio Resource Management Optimization of Flexible Satellite Payloads for DVB-S2 Systems

The increasing demand for high-rate broadcast and multicast services over satellite networks has pushed for the development of high throughput satellites characterized by a large number of beams (e.g., more than 100). This, together with the variable distr ...

ns-level time transfer over a microwave link using the PTP-WR protocol

Pierre-André Farine, Cyril Botteron, Jean-Pierre Aubry, Mathieu Paul Joseph Carlos Rico

Today it is possible to achieve sub-ns level time synchronization on a wireline network while only us-level synchronization can be achieved on a wireless (microwave) link. In this paper we will, first, study the performances of different time synchronizati ...

Diversity Gain Influenced by Polarization and Spatial Diversity Techniques in Ultrawideband

Anja Skrivervik, Mohsen Koohestani

This paper presents an experimental investigation of diversity gain influenced by polarization and spatial diversity techniques in ultrawideband (UWB) radio technology. To this aim, two different coplanar-fed UWB diversity antennas having the same size and ...

Efficient MAC in cognitive radio systems: A game-theoretic approach

Jean-Pierre Hubaux, Mark Felegyhazi, Mario Cagalj

In this paper, we study the problem of efficient medium access control (MAC) among cognitive radio devices that are equipped with multiple radios and thus are capable of transmitting simultaneously at different frequencies (channels). We assume that radios ...
