In this thesis we study Impulse-Radio Ultra-Wide Band (IR-UWB), a physical layer radio technology offering many features that make it a promising choice for future short-range wireless networks. The challenges in such networks are many, ranging from the co ...
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 ...
We propose a novel detection method for non-coherent synchronization in multi-access UWB impulse radio (IR) networks. It is designed to solve the IUI (Inter-User Interference) in particular the Near-Far scenario in the presence of concurrent UWB IR transmi ...
Multimedia services, audiovisual applications composed of a combination of discrete and continuous data streams, will be a major part of the traffic flowing in the next generation of high speed networks. The cornerstones for multimedia are Asynchronous Tra ...
We investigate the combined effect of application implementation method, container design, and efficiency of communication layers on the performance scalability of J2EE application servers by detailed measurement and profiling of an auction site server. We ...
We present a receiver design for joint interference suppression and
equalization of asynchronous multi–user space–time block coded (STBC) systems. We describe the design of front end prefilters to synchronize the received blocks from all users. Simulation ...
Multimedia services, audiovisual applications composed of a combination of discrete and continuous data streams, will be a major part of the traffic flowing in the next generation of high speed networks. The cornerstones for multimedia are Asynchronous Tra ...
Wireless Sensor Networks (WSNs) are composed of a large number of very small devices used for biomedical or environmental monitoring applications. These devices measure various natural processes at different locations, and cooperate in order to aggregate t ...
A new idea as well as CMOS implementation of a pulse-shaping filter useful in nuclear medicine to realize a multi-element detection by means of a multi-channel readout front-end ASIC have been presented. The filter changes the shape of pulses delivered by ...
Multiplexers are one of the most important elements in readout front-end ASICs for multi-element detectors in medical imaging. The purpose of these ASICs is to detect signals appearing randomly in many channels and to collect the detected data in an ordere ...
