11. Studies on Design and Implementation of Low-Complexity Digital Filters
Sammanfattning : In this thesis we discuss design and implementation of low-complexity digital filters. Digital filters are key components in most digital signal processing (DSP) systems and are, for example, used for interpolation and decimation. LÄS MER
12. Design Of Dual Polarisation Sideband Separation Mixer For ALMA Band 5
Sammanfattning : This licentiate is focused on the design and development of Superconductor-Insulator-Superconductor (SIS) junction mixer for ALMA Band 5, one of the ten frequency bands of the Atacama Large Millimeter Array (ALMA) project. ALMA Band 5 is a dual polarisation sideband separation heterodyne receiver covering radio frequencies (RF) from 163 GHz to 211 GHz, with 4-8 GHz intermediate frequency (IF). LÄS MER
13. Generalized Bandpass Sampling Receivers for Software Defined Radio
Sammanfattning : Based on different sampling theorem, for example classic Shannon’s sampling theorem and Papoulis’ generalized sampling theorem, signals are processed by the sampling devices without loss of information. As an interface between radio receiver front-ends and digital signal processing blocks, sampling devices play a dominant role in digital radio communications. LÄS MER
14. Tuneable Recursive Active Monolithic Microwave Integrated Circuit Filters
Sammanfattning : In this thesis tuneable recursive active monolithic microwave integrated circuit (MMIC) filters are studied theoretically and experimentally. A possible future application for such filters is, for example, the microwave receivers of adaptive radar antennas. LÄS MER
15. TDMA for Low Sampling Rate IR-UWB Receivers
Sammanfattning : In UWB communication sampling plays a key role in detection of the transmitted data. There are various methods of data transmission and detection at the receiver. Mostly, the detection methods are based on frequency domain methods. LÄS MER
