1. AURALIZATION, PERCEPTION AND DETECTION OF TYRE–ROAD NOISE
Sammanfattning : Due to improvements in combustion engines and electric engines for cars, tyre noise has become the prominent noise source at low and medium speeds. Models exist that simulate the noise produced by a rolling tyre, as do models that auralize specific traffic situations from a basic data set. LÄS MER
2. Optimal Detectors for Transient Signal Families and Nonlinear Sensors : Derivations and Applications
Sammanfattning : This thesis is concerned with detection of transient signal families and detectors in nonlinear static sensor systems. The detection problems are treated within the framework of likelihood ratio based binary hypothesis testing. LÄS MER
3. 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
4. Phase-Noise Compensation for Space-Division Multiplexed Multicore Fiber Transmission
Sammanfattning : The advancements of popular Internet-based services such as social media, virtual reality, and cloud computing constantly drive vendors and operators to increase the throughput of the Internet backbone formed by fiber-optic communication systems. Due to this, space-division multiplexing (SDM) has surfaced as an appealing technology that presents an opportunity to upscale optical networks in a cost-efficient manner. LÄS MER
