1. Adaptive MIMO Systems with Channel State Information at Transmitter
Sammanfattning : This dissertation presents adaptation techniques that can achieve high spectral efficiency for single user multiple-input multiple-output (MIMO) systems. Two types of adaptation techniques, adaptive modulation and adaptive powe allocation, are employed to adapt the rate and the transmit power to fading channels. LÄS MER
2. On interference suppression techniques for communication systems
Sammanfattning : The work presented in this thesis concerns interferencesuppression techniques in two different communication systems.In the first part we study fiber-optic systems with practical non-ideal transmitters and receivers, which give rise to intersymbol interference (ISI). LÄS MER
3. Studies of protein structure, dynamics and protein-ligand interactions using NMR spectroscopy
Sammanfattning : In the first part of the thesis, protein-ligand interactions were investigated using the chaperone LcrH, from Yersinia as target protein. The structure of a peptide encompassing the amphipathic domain (residue 278-300) of the protein YopD from Yersinia was determined by NMR in 40% TFE. LÄS MER

5. Post-translational modifications in DNA base excision repair : The roles of CK2 and PARP-1
Sammanfattning : Base lesions and DNA single-strand breaks (SSBs) are very common types of DNA damage. The base excision repair (BER) and single-strand break repair (SSBR) machineries both require a succession of enzymatic events in order to remove these types of endogenous lesions and to restore the DNA.
