21. Channel Coding and Multiuser Detection for CDMA and Wireless Communications
Sammanfattning : Next generation wireless communication systems will require support for many different applications as well as improved quality compared to existing second generation systems like GSM (Global System for Mobile communications). Since there will be more users and higher data rates, the capacity must also be increased. LÄS MER
22. 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.

23. Molecularly Imprinted Polymer Beads-Synthesis, Evaluation and Applications
Sammanfattning : Molecularly imprinted polymers (MIPs) are artificial receptors designed for the selective recognition of template molecules. These polymers have been applied in analytical separations, as chemical sensors and in drug delivery system due to their low cost and high stability. LÄS MER
24. The evolutionary ecology of plant reproductive diversity and floral signals : Mating system and floral scent in Arabis alpina
Sammanfattning : Flowering plants display an extraordinary floral- and reproductive diversity. Variation in the size, shape, colour and scent of flowers, and in systems and strategies of mating, is ubiquitous in comparisons of different species, but also exists among different conspecific populations.

25. Sequential convergence for functions and operators
Sammanfattning : The mathematical discipline homogenization theory is closely related to convergence issues. In this thesis different types of convergence are studied and put in relation to each other. We consider the classical concepts of G- and H-convergence and compensated compactness. LÄS MER
