1. The Random Line-of-Sight Over-the-Air Measurement System
Sammanfattning : As our society becomes increasingly connected, a growing number of devices rely on wireless connectivity. The type, use and form factor of these devices range from wearables to entire vehicles. Additionally, the fifth generation of wireless communication (5G) introduces new communication bands, also at higher frequencies. LÄS MER
2. Over-the-Air Computation for Machine Learning: Model Aggregation via Retransmissions
Sammanfattning : With the emerging Internet of Things (IoT) paradigm, more than a billion sensing devices will be collecting an unprecedented amount of data. Simultaneously, the field of data analytics is being revolutionized by modern machine learning (ML) techniques that enable sophisticated processing of massive datasets. LÄS MER
3. Over-the-Air Performance Estimation of Wireless Device Antennas
Sammanfattning : This thesis work presents studies on the available measurement methods for estimating the over-the-air (OTA) performance of wireless device antennas. This thesis is divided into two parts. LÄS MER
4. Verification of wireless communication performance and robustness for automotive applications
Sammanfattning : Today's test methods used for verifying the performance and robustness of automotive applications using wireless communication are often based on fieldtrails, which are time consuming, costly, and not repeatable. Therefore, there is an urgent need for new verification methods that can be performed in lab environment, where the realistic radio propagation environment can be emulated. LÄS MER
5. Evaluation of the Random-LOS Measurement System for Vehicular Communication Applications
Sammanfattning : The automotive industry is progressively closing on the Telecom industry as wireless data connection and transmission become more and more important for vehicles. In both future and present cars, the safety and infotainment systems depend on reliable wireless data transmission. This is especially the case when autonomous cars will reach the market. LÄS MER
