1. Evaluation and Optimization of LTE-V2X Mode 4 under Aperiodic Messages of Variable Size
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : Vehicular networks connect vehicles for improved road safety and efficiency with the assistance of wireless information exchange. Vehicular networks are based on the frequent broadcast of awareness messages referred to as CAM (Cooperative Awareness Messages) or BSM (Basic Safety Message) in the ETSI and SAE standards, respectively.

2. Digital Front End Algorithms for Sub-Band Full Duplex
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.

3. Near Field millimeter Wave Antenna Measurements
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : In the real world, understanding an antenna's radiation pattern is crucial for its proper utilization. Typically, antennas are tested in the far-field region, where the radiation lobes are fully developed and phase errors are less than pi/8. LÄS MER
4. Machine learning based call drop healing in 5G
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : Self-Organizing Network (SON) functions include self-configuration, dynamic optimization and self-healing of networks. In the era of 5G, mobile operators are increasingly exploring areas of SON through Machine Learning (ML) techniques. LÄS MER
5. Beamforming Solutions for Efficient Link Setup and Link Maintenance in mmWave Communication Systems
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : Millimeter wave (mmWave band) technology has gained a lot of attention in 5G communications, due to large amounts of spectrum being available in the mmWave frequency range. However, mmWave links suffer from severe free-space loss and atmospheric absorption. LÄS MER
