1. A new approach for considering the interference impact on digital radio systems from complex interference environments
Sammanfattning : Interference from electrical equipment can severely degrade aco-located digital radio receiver. To avoid such performance degradation, it isnecessary to have estimation methods to predict the influence of an interferenceenvironment on a radio receiver. LÄS MER
2. On Performance of Digital Radio Receiver in Non-Gaussian Interference
Sammanfattning : Interference from electrical equipment can degrade a co-located digital radio receiver severely. To avoid this performance degradation it is necessary to have estimation methods to predict the influence from an interference environment on a radio receiver in advance. LÄS MER
3. Urban Area Information Extraction From Polarimetric SAR Data
Sammanfattning : Polarimetric Synthetic Aperture Radar (PolSAR) has been used for various remote sensing applications since more information could be obtained in multiple polarizations. The overall objective of this thesis is to investigate urban area information extraction from PolSAR data with the following specific objectives: (1) to exploit polarimetric scattering model-based decomposition methods for urban areas, (2) to investigate effective methods for man-made target detection, (3) to develop edge detection and superpixel generation methods, and (4) to investigate urban area classification and segmentation.

4. Signal Design for Active Sensing and Communications
Sammanfattning : Man-made active sensing systems such as active radar and sonar have been a vital part of our civilization's advancement in navigation, defense, meteorology, and space exploration. Modern active sensing systems rely heavily on the significant progress in the science and technology of communications made within the last century. LÄS MER
5. Integrated Circuit Solutions for High Datarate Polymer Fiber Communication
Sammanfattning : Most societies today are dependent on an Internet connection. It has to be reliable in any condition, energy efficient, but most importantly fast. High data rate communication is urgently needed, not only to connect one part of the world to the other, but also for short range applications to help us get through the day. LÄS MER
