6. Design of High-Speed Time-Interleaved Delta-Sigma D/A Converters
Sammanfattning : Digital-to-analog (D/A) converters (or DACs) are one the fundamental building blocks of wireless transmitters. In order to support the increasing demand for highdata-ate communication, a large bandwidth is required from the DAC. LÄS MER
7. On High-Speed Digital-to-Analog Converters and Semi-Digital FIR Filters
Sammanfattning : High-speed and high-resolution digital-to-analog converters (DACs) are vital components in all telecommunication systems. Radio-frequency digital-to-analog converter (RFDAC) provides high-speed and high-resolution conversion from digital domain to an analog signal. RFDACs can be employed in direct-conversion radio transmitter architectures. LÄS MER
8. Enhanced image analysis, a tool for precision metrology in the micro and macro world
Sammanfattning : The need for high speed and cost efficient inspection in manufacturing lineshas led to a vast usage of camera-based vision systems. The performance ofthese systems is sufficient to determine shape and size, but hardly to an accuracylevel comparable with traditional metrology tools. LÄS MER
9. Synthetic Aperture Radar Signal and Image Processing for Moving Target Indication and Side Lobe Suppression
Sammanfattning : The thesis summarizes a selection of my research within Synthetic Aperture Radar (SAR). Mainly the research is aimed at applying and developing signal processing methods to single channel and multi channel SAR for wideband systems. SAR systems can generate images looking very similar to optical pictures, i.e. LÄS MER
10. Development and evaluation of SAR algorithms for image formation and speed estimation in wideband SAR
Sammanfattning : Remote sensing and surveillance are the main application areas for radar in general and synthetic aperture (SAR) radar in particular. Since the first radar system built by Hülsmeyer in 1904, radar has developed so that it is now able to create images from a large distance. LÄS MER
