This paper presents an analysis of sound speed distribution in the Mediterranean Sea based on climatological 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)
The provision of high capacity, low cost and reliable wireless multimedia communication for bursty packet traffic (as well as voice and delay constrained streaming traffic) continues to be a challenging aspect of future wireless communications systems. In this sense, structured and ad-hoc multihop networks and intelligent relaying are expected to play a(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)
The solution addressed here is based on inertial navigation: the output (linear acceleration and angular velocity) of a small-size inertial measurement unit, weared by the operator to be tracked, is processed to estimate the present location and the walked path. This information can be transmitted outside the intervention area, e.g. to the manager of the(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)
