1. Radio Channel Prediction Based on Parametric Modeling
Sammanfattning : Long range channel prediction is a crucial technology for future wireless communications. The prediction of Rayleigh fading channels is studied in the frame of parametric modeling in this thesis.Suggested by the Jakes model for Rayleigh fading channels,deterministic sinusoidal models were adopted for long rangechannel prediction in early works.

2. Spectrum Sensing Algorithms Based on Second-Order Statistics
Sammanfattning : Cognitive radio is a new concept of reusing spectrum in an opportunistic manner. Cognitive radio is motivated by recent measurements of spectrum utilization, showing unused resources in frequency, time and space. Introducing cognitive radios in a primary network inevitably creates increased interference to the primary users. LÄS MER
3. Signal Processing Aspects of Bistatic Backscatter Communication
Sammanfattning : Passive Internet-of-Things (IoT), a new paradigm based on battery-free devices, is a promising technology to enable several use cases that require connectivity with stringent requirements in terms of cost, complexity, and energy efficiency. These use cases span critical sectors, such as healthcare, transportation, and agriculture. 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. Bayesian Inference with Unknown Noise Covariance
Sammanfattning : This thesis studies Bayesian methods in statistical signal processing. A central theme is that the treatment of the unknown noise covariance matrix is of chief concern for all scenarios. As a first application, the detection of land mines using infrared techniques is investigated. LÄS MER
