1. On the Design of Communication Systems for Strong Oscillator Phase Noise - Detection Methods and Constellation Optimization
Sammanfattning : The problem of designing wireless communication systems to operate in the presence of oscillator phase noise is a classical problem in communication theory. In recent times, there has been a renewed interest in thisproblem for a multitude of reasons. LÄS MER
2. On the Impact of Phase Noise in Communication Systems –- Performance Analysis and Algorithms
Sammanfattning : The mobile industry is preparing to scale up the network capacity by a factor of 1000x in order to cope with the staggering growth in mobile traffic. As a consequence, there is a tremendous pressure on the network infrastructure, where more cost-effective, flexible, high speed connectivity solutions are being sought for. LÄS MER
3. Detection of signals corrupted by non-gaussian disturbances
Sammanfattning : The detection of signals in additive, non-Gaussian disturbances is the main theme of this thesis. The disturbances are modeled either by non-Gaussian noise or by Gaussian noise in combination with intersymbol or co-channel interference. LÄS MER
4. Model Selection and Sparse Modeling
Sammanfattning : Parametric signal models are used in a multitude of signal processing applications. This thesis deals with signals for which there are many candidate models, and it is not a priori known which model is the most appropriate one. LÄS MER
5. On Nonlinear Compensation Techniques for Coherent Fiber-Optical Channel
Sammanfattning : Fiber-optical communication systems form the backbone of the internet, enabling global broadband data services. Over the past decades, the demand for high-speed communications has grown exponentially. One of the key techniques for the efficient use of existing bandwidth is the use of higher order modulation formats along with coherent detection. LÄS MER
