1. Method development for co-simulation of electrical-chemical systems in Neuroscience
Sammanfattning : Multiscale modeling and simulation is a powerful approach for studying such phenomena in nature as learning and memory. In computational neuroscience, historically, methods and tools for neuronal modeling and simulations have been developed for studies focused on a single level of the neuronal organization. LÄS MER
2. Frequency Analysis of Sampled-Data Systems Applied to a Lime Slaking Process
Sammanfattning : Single-rate and multirate sampled-data (SD) systems as well as linear time periodic (LTP) systems with discrete jumps are analyzed in the frequency domain. The focus of the analysis is both on rejection of disturbances and on robust stability properties. LÄS MER
3. Multirate Schemes and Multiuser Decoding in DS/CDMA Systems
Sammanfattning : Direct-Sequence Code Division Multiple-Access (DS/CDMA) has for some yearsbeen considered as a candidate for future personal and mobile communications.The reasons are mainly the properties of universal frequency reuse andthe multi-path mitigation. LÄS MER
4. Contributions to Flexible Multirate Digital Signal Processing Structures
Sammanfattning : A current focus among communication engineers is to design flexible radio systems in order to handle services among different telecommunication standards. Efficient support of dynamic interactive communication systems requires flexible and cost-efficient radio systems. LÄS MER
5. Multirate Codes and Multicarrier Modulation for Future Communication Systems
Sammanfattning : In this thesis, new detection and modulation methods for multicarrier systems are presented. The proposed multicarrier detectors are based on feedback of previously detected symbols and the idea is to exploit the correlation, both in time between consecutive symbols, and in frequency between neighboring sub-carriers.
