Optimization of multimedia transmissions over wireless channels should be aimed at maximizing the video quality perceived by the final user. For transmission of video sequences over an orthogonal frequency division multiplexing (OFDM) system in a slowly va ...
Iterative detection and decoding (IDD), combined with spatial-multiplexing multiple-input multiple-output (MIMO) transmission, is a key technique to improve spectral efficiency in wireless communications. In this paper we present the—to the best of our know ...
Wireless mesh networks were designed as a mean to rapidly deliver large-scale communication capabilities without the support of any prior infrastructure. Among the different properties of mesh networks, the self-organizing feature is particularly interesti ...
Energy-detection (ED) receivers can take advantage of the ranging and multipath resistance capabilities of impulse-radio ultra-wideband (IR-UWB) physical layers at a much lower complexity than coherent receivers. However, ED receivers are extremely vulnera ...

This paper describes a receiver system design for impulse-radio ultra-wideband (IR-UWB) that operates at two carrier frequencies-3.494 and 3.993 GHz-with a 10-Mbps data rate. To reduce the power consumption of the front-end amplifiers, a super-regenerative ...
HomePlug AV (HPAV) was designed to provide high speed in-home communication with 200Mbps PHY rate, with the goal to overcome various noises over power wires and to jump from one phase to a neighboring one. A HomePlug AV Logical Networks (AVLN) is defined b ...

We describe an impulse-radio ultra-wideband (IR-UWB) transmitter made with off-the-shelf discrete components. It was initially designed to be used in a UWB testbed for measurement and algorithm validation purposes. There already exist several versions of a ...

As wireless and mobile technologies are becoming increasingly pervasive, an uninterrupted connectivity in mobile devices is becoming a necessity rather than a luxury. When dealing with challenged networking environments, this necessity becomes harder to ac ...
In this paper, we consider the K-user Gaussian multiple-access channel with multiple independent additive white Gaussian interferences. Each interference is known to exactly one transmitter non-causally. The capacity region is characterized to within a bou ...
