Abstract—In this paper, a novel architecture for a low data-rate, low power consumption Impulse Radio (IR) Ultra- Wideband (UWB) receiver is presented in which the received UWB signal is downconverted to a given intermediate frequency (IF) rather than at b ...
The robustness of the delivery of digital compressed video streams has always been one of the main topic of the standardization bodies to assure the Quality of the Service (QoS). The MPEG standard which is nowadays the reference for digital television defi ...
Recently, there has been considerable discussion about new wireless technologies and standards able to achieve high data rates. Due to the recent advances of digital signal processing and Very Large Scale Integration (VLSI) technologies, the initial obstac ...
Orthogonal frequency division multiplexing (OFDM) is a widely recognized modulation scheme for high data rate communications. However, the implementation of OFDM-based systems suffers from in-phase and quadrature-phase (IQ) imbalances in the front-end anal ...
The paper gives an information theoretic analysis of the potential of chaos in digital communication schemes, underlining that there is no fundamental principle that speaks against the use of chaotic systems in digital communications. The channel model con ...
The transceivers of a wireless sensor network (WSN) have to fulfill the low-power and low-voltage constraints. The WiseNET project has already proven that it is possible to design a receiver working at 1V and consuming less than 2mW. However this transceiv ...
Multiplexers are one of the most important elements in readout front-end ASICs for multi-element detectors in medical imaging. In the paper a fully asynchronous multiplexer with limited hierarchical de-randomization mechanism has been presented. The hierar ...
The paper describes the state of the art in the design of receivers for chaos based digital communication over noisy channels. In the first part, an information theoretic analysis of the potential of chaos in digital communication schemes is given, underli ...
This thesis treats the topic of chaos based broadband communication schemes, with particular emphasis on the statistical analysis and optimization of such schemes. The work is motivated by the recent advances in nonlinear system theory suggesting advantage ...
This paper studies the tracking performance of adaptive filters operating in the presence of two sources of nonstationarities: carrier frequency offsets and random channel variations. Both impairments are common in digital communications due to mismatches ...
