This paper presents an analysis of sound speed distribution in the Mediterranean Sea based on climatologi-cal temperature and salinity data. In the upper layers, propagation is characterised by upward refraction in winter and an acoustic channel in summer. The seasonal cycle of the Mediterranean and the presence of gyres and fronts create a wide range of(More)
Multi-element arrays at both ends of a communication link (Multiple Input Multiple Output – MIMO) have the potential of increasing the throughput and/or of improving the link reliability through spatial diversity. In this paper the capability of increasing the throughput in HIPERLAN/2 (H/2) Wireless LAN (WLAN) standard by MIMO Spatial Multiplexing is(More)
In this paper the Passive Ocean Acoustic Tomography (P-OAT) methodology is presented. This technique, avoiding the use of a dedicated active sound source, estimates the sea water temperature spatial distribution from the received noise emitted from ships of opportunity. The feasibility of the proposed methodology has been confirmed both by test-runs on(More)
The layout of the RPCs, used in the Argo-YBJ experiment to image with a high space-time granularity the atmospheric shower, is described in this paper. The detector has been assembled to provide both digital and analog informations in order to cover a wide particle density range with a time accuracy of 1 ns. The experimental results obtained operating the(More)
A future network deployment is given by a cell with a base station (BS) and a second tier of femtocells: a femtocell is a short-range mini-BS to be mainly deployed indoor to improve coverage and bandwidth by forwarding traffic on an IP backhaul link. However, the mutual interference arising between femtocells and mobile equipments or BS can become a(More)
The FP7 ROCKET project aims at designing Broadband Wireless Access (BWA) technology that enables a larger number of users to be served at a high data rate in both urban and rural deployment scenarios. The technical approach relies on the combination of 1)advanced coordination and cooperation of Base Stations (BS) and Relay Stations (RS) in order to increase(More)
