— This paper proposes a simple co-decoding scheme for a Writing on Dirty Paper scenario, where the transmitted signal is affected by interference known by the transmitter and thermal noise. We focused on rate-1/2 codes, suitable for low SNR regions, but the scheme is easily generalizable to different code rates. In particular our approach involves a proper(More)
A content adaptive, network aware approach for joint optimization of wireless video transmission is presented in this paper. The joint system optimization approach has been developed in the framework of the IST PHOENIX project (www.ist-phoenix.org). After a description of the considered cross-layer approach and of the information to be exchanged among the(More)
— A radar sensor network (RSN) is a wireless network system, typically composed of one transmitting (TX) node and several receiving (RX) nodes, aimed at detecting and tracking an intruder (target) moving within a given surveillance area. In this paper, RSNs based on impulse radio ultra-wideband (UWB) are investigated. In the considered system, at each(More)
Future wireless video transmission systems will consider orthogonal frequency division multiplexing (OFDM) as the basic modulation technique due to its robustness and low complexity implementation in the presence of frequency-selective channels. Recently , adaptive bit loading techniques have been applied to OFDM showing good performance gains in cable(More)
End-to-end optimised Quality of Service (QoS) and its specific declination for multimedia applications with the end-user Perceived Quality of Service (PQoS) is nowadays a trendy topic in the literature. Many different techniques and approaches have been proposed, which are in general focusing on specific weak technical aspects of the transmission chain in(More)
—Different design issues and performance aspects of a low-complexity echo canceller for digital on-channel repeaters are described in this paper. Locally generated pulse trains are injected in the repeated signal to estimate the coupling channel between the transmitting and the receiving antennas. In particular, we analyze a low-complexity channel(More)
— A software platform for demonstration and performance evaluation of network aware joint optimization of wireless video transmission is presented in this paper. This demonstrator has been realized in the framework of the IST PHOENIX project (www.ist-phoenix.org) and is based on the joint system optimization model developed by the project. After a(More)
