1. Maximum likelihood detection for the linear MIMO channel
Sammanfattning : this thesis the problem of maximum likelihood (ML) detection for the linear multiple-input multiple-output (MIMO) channel is considered. The thesis investigates two algorithms previously proposed in the literature for implementing the ML detector, namely semide nite relaxation and sphere decoding. LÄS MER
2. 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
3. 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
4. Analysis of Relay Channels and Improved Iterative Decoders for Turbo-Coded Decode-and-Forward Relay Channels
Sammanfattning : Three-node relay channels which consist of a source, a relay and a destinationare considered in this thesis. In the first part, an uncoded relay channelis studied. LÄS MER
