1. Detection in Digital Communication Systems with Phase Noise
Sammanfattning : In every communication system, the limitations of the hardware sets a constraint on the overall system performance. More often than not, these limitations are not taken into account during the system design stage where the hardware is considered ideal. LÄS MER
2. Numerical Approximation of Solutions to Stochastic Partial Differential Equations and Their Moments
Sammanfattning : The first part of this thesis focusses on the numerical approximation of the first two moments of solutions to parabolic stochastic partial differential equations (SPDEs) with additive or multiplicative noise. More precisely, in Paper I an earlier result (A. Lang, S. Larsson, and Ch. LÄS MER
3. On Bit-Wise Decoders for Coded Modulation
Sammanfattning : Coded modulation is a technique that emerged as a response to the growing demand for high data rates. It was devised to achieve high spectral efficiency with high reliability, potentially approaching Shannon’s capacity. The main idea of coded modulation consists in combining error-correcting coding with higher-order modulation. LÄS MER
4. On Deterministic Models for Gaussian Networks
Sammanfattning : In this thesis we study wireless networks modeled by the additive white Gaussian noise (AWGN) model. The AWGN capacity region of most network topologies is unknown, which means that the optimal transmission scheme is unknown as well. This motivates the search for capacity approximations and for approximately optimal schemes. LÄS MER
5. Spectrally Efficient Continuous Phase Modulation
Sammanfattning : Spectrally efficient continuous phase modulation (CPM) systems and generalizations of CPM for wireless links are considered. Continuous phase modulation defines constant envelope phase codes, which are advantageous when using non-linear amplifiers. LÄS MER
