1. Heart rate estimation from wrist-PPG signals in activity by deep learning methods
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : In the context of health improving, the measurement of vital parameters such as heart rate (HR) can provide solutions for health monitoring, prevention and screening for certain chronic diseases. Among the different technologies for HR measuring, photoplethysmography (PPG) technique embedded in smart watches is the most commonly used in the field of consumer electronics since it is comfortable and does not require any user intervention.

2. Performance of UE Relaying for 6G Networks
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Throughout the evolution of communication networks, users have consistently been demanding additional data and coverage. Future 6G networks seek to enable a seamless cyber-physical world through interconnected and integrated connectivity. LÄS MER
3. Beamformed Channel Matrix Positioning using 5G Testbench CSI data with a Deep-Learning Pipeline
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : Within the telecommunications industry, a positioning system for estimating user equipment (UE) location using purely information available for the basestation has an enormous number of potential uses. The link between physical position and the network channel state enables potential positioning systems to function by under- standing the network channel state dependency on location, using a model-based, data-based, or a combined approach.

4. Faster than Nyquist Signaling with Spatial Coupling
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : The emergence of the Faster-Than-Nyquist signaling (FTN) technology has im- proved the tight spectrum resources by compressing the transmission interval between adjacent pulses. In a natural environment, data transmission via a wire- less medium and through multi-path, at a high data rate, the leakage of these paths among symbols can cause severe inter-symbol interference (ISI).

5. Towards Embedded Implementations of Multi-Armed Bandit Algorithms for Optimised Channel Selection
Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologiSammanfattning : The proliferation of Internet of Things increases the demand for achieving a high performance for embedded devices on the Internet. The IEEE 802.15.4 wireless network standard provides ultra low complexity, cost, power consumption and data rate for inexpensive devises, although it has problems such as external interference and multi-path fading.
