1. Fractional Fourier Transform and Scaling Problem in Signals and Images
Magister-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandlingSammanfattning : Context: We identify a material or thing that can be seen and touched in the world as having structures at both coarser and finer levels of scale. Scaling problem presents in a branch of science concerned with the description, prediction understanding of natural phenomena and visual arts. LÄS MER
2. Image Reconstruction using wavelet transform with extended fractional fourier Transform
Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandlingSammanfattning : Image reconstruction forms the basis of many applications in the fields of medicine, astronomy etc. Historically an image is reconstructed using several methods of which Fourier and wavelet transform methods formed the roots of present day technologies.

3. Locating Unknown Wireless Devices Using Stimulated Emissions and the Fractional Fourier Transform
Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)Sammanfattning : Unknown wireless devices that use receiver architectures with a mixer may be detected and located using stimulated emissions. Transmitting a known stimulation signal and correlating leaked mixer products allows measurement of the TOF and thus range. LÄS MER
