1. 26. Statistical tools for ultrasonic analysis of dispersive fluids

   Författare :Jesper Martinsson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

   Sammanfattning : This thesis focuses on the possibility of using ultrasonic measurement techniques for energy gas characterization. The idea is to combine both on-line flow measurements with non-invasive fluid characterization in the same measurement setup using the same sensor(s). LÄS MER

3. 27. Statistical Analysis of Hardware Impairments in Communication Systems

   Författare :Mohammad Hossein Moghaddam; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hardware impairments; distortion analysis; PA nonlinearity; phase noise; spectral analysis; pulse shaping and matched filter; IQI;

   Sammanfattning : This thesis delves into the study of hardware impairments, the inevitable limiting factors in radio frequency (RF) communication systems, and their substantial influence on system performance. It addresses the incongruity between the often stringent requirements imposed by standards and the innate imperfections of analog circuits present in real-world RF electronics. LÄS MER

4. 28. Quantization of Random Processes and Related Statistical Problems

   Författare :Mykola Shykula; Oleg Seleznjev; Patrik Rydén; Igor Rychlik; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; scalar quantization; random process; rate; distortion; additive noise model; run-length encoding; compression; sample estimate; asymptotical normality; Mathematical statistics; Matematisk statistik;

   Sammanfattning : In this thesis we study a scalar uniform and non-uniform quantization of random processes (or signals) in average case setting. Quantization (or discretization) of a signal is a standard task in all nalog/digital devices (e.g., digital recorders, remote sensors etc. LÄS MER

5. 29. Flexible wireless receivers : on-chip testing techniques and design for test

   Författare :Ramzan Rashad; Fenghao Mu; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : In recent years the interest in the design of low cost multistandard mobile devices has gone from technical aspiration to commercial essential. Usually, the emerging wireless applications prompt the conception of new wireless standards. The end user wants to access voice, data, and streaming media from single wireless terminal. LÄS MER

7. 30. Performance Analysis and Deployment Techniques forWireless Sensor Networks
