Accurate measurement and monitoring of precipitation is crucial for many applications, such as flood and drought risk assessment and management. Conventional meteorological devices for estimating precipitation (i.e., rain gauges, disdrometers, active and passive remote sensors, be they ground-based, spaceborne, or airborne) have their own strengths...

In future communication satellite systems the adoption of higher frequencies as Q/V-band (around 40 GHz for downlink and 50 GHz for uplink) is seen as the promising step forward to achieve higher performance in terms of total system throughput. The envisaged usage of these frequency bands, bringing an additional 5 GHz bandwidth in each polarization...

We present the NEFOCAST project (named by the contraction of "Nefele", which is the Italian spelling for the mythological cloud nymph Nephele, and "forecast"), funded by the Tuscany Region, about the feasibility of a system for the detection and monitoring of precipitation fields over the regional territory based on the use of a widespread network...

Software Defined Radio (SDR) is currently one of the main topics of interest in military communications, as well as in civil ones. Since 2002, the Italian Ministry of Defense (MoD) has identified the SDR technology as a strategic capability. In this respect, Italy has become part of the major multinational programs related to military SDR and wavef...

This paper deals with the power allocation problem in a multipoint-to-multipoint network, which is heterogenous in the sense that each transmit and receiver pair can arbitrarily choose whether to selfishly maximize its own rate or energy efficiency. This is achieved by modeling the transmit and receiver pairs as rational players that engage in a no...

In this lecture note, we introduce the basic concepts of game theory (GT), a branch of mathematics traditionally studied and applied in the areas of economics, political science, and biology, which has emerged in the last fifteen years as an effective framework for communications, networking, and signal processing (SP). The real catalyzer has been...

This work develops power control algorithms for bit/Joule energy efficiency (EE) maximization in wireless networks.

Both network-c...

SDR is today one of the most appealing technology both for military and commercial market. Among the main benefits of SDR there are flexibility and portability, given by the possibility to develop Waveform (WF) independently from the platforms where they will be hosted. this makes the signal processing completely decoupled from the RF hardware. For...

We apply non-binary coding to the two-way relay channel and evaluate two decoding schemes for the multiple-access phase at the relay: joint decoding for both users and separate decoding for a linear combination of both packets. We evaluate several efficient modulation schemes which combine favorably with non-binary coding and find that joint decodi...
