1. Laboratory starlight simulator for future space-based heterodyne interferometry
University essay from Luleå tekniska universitet/RymdteknikAbstract : In astronomy, interferometry by ground-based telescopes offers the greatest angular resolution. However, the Earth´s atmosphere distorts the incident wavefront from a celestial object, leading to blurring and signal loss. It also restricts the transmission of specific wavelengths within the electromagnetic spectrum. READ MORE

3. Beam refinement and beam tracking using Machine Learning Techniques in 5G NR RAN
University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskapAbstract : Abstract: Growing needs of communication, demands a higher data transmission rate in 5G NR. In the 3rd generation partnership project (3GPP), frames are used to schedule the data to be transferred between the cellular base station (gNB) and user equipment (UE). READ MORE

4. Assessment of weather conditions for ALMA observations of the Sun
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : The closest star to Earth is the Sun. The difference between our Sun and other stars is that the dynamics are observable with telescopes. A complex and strange part of our Sun is the chromosphere which is a part of the solar atmosphere.

5. Reinforcement Learning for Link Adaptation in 5G-NR Networks
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The Adaptive Modulation and Coding (AMC) scheme in the link adaptation is a core feature in the current cellular networks. In particular, based on Channel Quality Indicator (CQI) measurements that are computed from the Signal-to-Interference-plus-Noise Ratio (SINR) level of User Equipment (UE), the base station (e.g. READ MORE
