1. Joint CFR and DPD optimization for 5G Digital Front Ends
University essay from Lunds universitet/Matematik LTHAbstract : This thesis project investigates the topic of joint optimization for crest factor reduction and digital predistortion blocks, which are used for digital correction of analogue impairments in digital radio front ends. The work first investigates the effects of joint parameter variation of the above blocks on the global performance and computational cost of the digital chain, given reference CFR and DPD algorithms.

2. Statistics of Electric and Magnetic Fields at the Earth’s Bow Shock
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The interaction between the solar wind and Earth’s magnetic field creates the Earth’s bow shock. It is an ideal region for space probes like MMS, THEMIS or Clusters to study the collisionless shock phenomenon in space plasma. READ MORE

3. Wide-Angle Radome Design for Low-Cost Additive Manufacturing
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : The radome, a portmanteau of the words radar and dome, is a protective dielectric cover to protect a radar from its surrounding environment. The surrounding environment can be rain, wind, sand, dust and whatever else that might harm the radar. READ MORE

4. High-Performance Beamforming for Radar Technology : A Comparative Study of GPU Beamforming Algorithms
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Radar technology is widely used in today´s society, whether it is the localisation and identification of aircraft in air traffic control systems, ships in harbour management systems, or the weather forecast presented on the news. In military applications, such as in fighter jets or missile lock-on systems, the speed at which the radar processes incoming data is essential to ensure a successful outcome. READ MORE

5. Evaporation Duct Modelling for a Wave-Propagation Simulator
University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Abstract : Long-range communication proves to be a challenge due to the Earth’s curvature, since electromagnetic waves propagate away from the Earth’s surface in a free atmosphere. A possible solution to beyond line-of-sight communication is the atmospheric phenomenon known as the evaporation duct. READ MORE
