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. Multiuser detection in CDMA : combinatorial optimization methods
Sammanfattning : .... LÄS MER
3. Spectral Analysis of Nonuniformly Sampled Data and Applications
Sammanfattning : Signal acquisition, signal reconstruction and analysis of spectrum of the signal are the three most important steps in signal processing and they are found in almost all of the modern day hardware. In most of the signal processing hardware, the signal of interest is sampled at uniform intervals satisfying some conditions like Nyquist rate. LÄS MER
4. Detection and Classification in Electrocardiac Signals
Sammanfattning : Signal processing can be used to condition medical signals to facilitate their interpretation, and to extract clinically important information. The purpose of the present doctoral thesis is to put forward solutions to certain problems encountered in the processing of electrocardiac signals. LÄS MER
5. 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
