A cognitive radio (CR) network is reliable by the ability of the secondary user (SU) to maximize the spectrum usage while minimizing the interference on the primary user (PU). This depends on how sensing and transmission are scheduled by the SU. In t [...]

One important problem in spectrum sensing is to detect a noisy and unknown signal, while keeping the risk of detection error as low as possible. This problem may be accentuated in mobile environments due to fast situation changes. In this paper, we c [...]

Structural health monitoring has recently attracted much attention in research and development thanks to distributed optical fibre sensors. Among distributed optical fibre sensors, phase-sensitive optical timedomain reflectometry (φ-OTDR) allows dist [...]

DVB-T2 is the second generation of terrestrial broadcasting standard widely adopted or deployed in Europe and Africa. During the network planning, the channel propagation is the challenging element for broadcasters. As it is known to be probabilistic [...]
