1. The ubiquitous signal processing : Applications to communications, spectral analysis and array processing
Detta är en avhandling från Uppsala : Acta Universitatis UpsaliensisSammanfattning : This dissertation is concerned with statistical signal processing and its applications. The thesis consists of three parts: I) applications to wireless communications, II) applications to spectral analysis and III) applications to array processing. LÄS MER
2. Signal Processing Techniques in Mobile Communication Systems Signal Separation, Channel Estimation and Equalization
Detta är en avhandling från Ronneby : Blekinge Institute of TechnologySammanfattning : Over the last decade there has been an explosive growth in the use of wireless mobile communications. Second generations systems are mature technologies now and third generation systems and beyond are being implemented and researched. LÄS MER
3. Speech Signal Extraction A Multichannel Approach
Detta är en avhandling från Printed by Lund University, ReprocentralenSammanfattning : In speech signal extraction the aim is to extract human speech in a physical environment by using microphones. In any real world environment there are many disturbance sources that cause unwanted sound pressure, which in turn may degrade the comprehension of the speech at the microphones. LÄS MER
4. Multichannel Audio Signal Processing : Room Correction and Sound Perception
Detta är en avhandling från Uppsala : Acta Universitatis UpsaliensisSammanfattning : This thesis concerns and combines multichannel sound reproduction, digital room correction, audio signal processing, and human sound perception. It investigates perceived sound quality and new methods to improve timbral and spatial fidelity of loudspeaker-based multichannel sound reproduction in reverberant environments. LÄS MER
5. Signal Processing for Spectroscopic Applications
Detta är en avhandling från Uppsala : Acta Universitatis UpsaliensisSammanfattning : Spectroscopic techniques allow for studies of materials and organisms on the atomic and molecular level. Examples of such techniques are nuclear magnetic resonance (NMR) spectroscopy—one of the principal techniques to obtain physical, chemical, electronic and structural information about molecules—and magnetic resonance imaging (MRI)—an important medical imaging technique for, e.
