1. Polarization-Mode Disperion in Optical Fibers: Characterization, Transmission Impairments, and Compensation
Sammanfattning : The topic of this thesis is polarization-mode dispersion (PMD) in optical fibers and its impact on high-speed data transmission. The work can be divided into three parts which deal with the major aspects of PMD: characterization, transmission properties and compensation. LÄS MER
2. Modeling and Compensation of Polarization Effects in Fiber-Optic Communication Systems
Sammanfattning : Optical communication systems that exploit the orthogonality between two polarizations of light convey information over optical fibers by modulating data over the two polarizations. In an idealized scenario, the two polarizations propagate through the fiber without interfering. LÄS MER

Sammanfattning : .... LÄS MER
4. On the biology of premenstrual dysphoria and panic disorder
Sammanfattning : Premenstrual dysphoria (PMD) afflicts 7% of all women of fertile age, and is characterized by symptoms such as irritability, sadness, and mood swings, appearing regularly before menstruation, and being of such severity that they markedly reduce quality of life. The symptoms are dependent of sex steroids, and seem to be under the influence of serotonin, since they respond to treatment with serotonin reuptake inhibitors (SRIs). LÄS MER
5. Digital Dispersion Equalization and Carrier Phase Estimation in 112-Gbit/s Coherent Optical Fiber Transmission System
Sammanfattning : Coherent detection employing multilevel modulation format has become one of the most promising technologies for next generation high speed transmission system due to the high power and spectral efficiencies. With the powerful digital signal processing (DSP), coherent optical receivers allow the significant equalization of chromatic dispersion (CD), polarization mode dispersion (PMD), phase noise (PN) and nonlinear effects in the electrical domain.
