— 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)
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)
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)
M-health is an emerging area of research and one of the key challenges in future research in this area is medical video streaming over wireless channels. Contrasting requirements of almost lossless compression and low available bandwidth have to be tackled in medical quality video streaming in ultrasound and radiology applications. On one side, compression(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)
A multistatic radar based on ultra-wideband (UWB), also known as a UWB radar sensor network, has been shown to represent a very promising solution to localize an intruder moving within a small surveillance area. In this paper, a tracking algorithm based on low-complexity particle filtering is proposed, specifically tailored to UWB radar sensor networks with(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)
This paper examines the problems of dirty-paper and dirty-tape coding with some additional side information (SI) at the decoder. In particular we focus on the situation in which the decoder SI is a noisy version of the SI at the encoder. We show that noisy SI at the decoder is advantageous for many channels in terms of capacity and, in general, the optimal(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)
