1. Re-synthesis of instrumental sounds with Machine Learning and a Frequency Modulation synthesizer
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Frequency Modulation (FM) based re-synthesis to find the parameter values which best make a FM-synthesizer produce an output sound as similar as possible to a given target sound is a challenging problem. The search space of a commercial synthesizer is often non-linear and high dimensional. LÄS MER
2. Digitally Controlled Oscillator for mm-Wave Frequencies
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : In the fifth generation of mobile communication, 5G, frequencies above 30 GHz, so-called millimeter-wave (mm-wave) frequencies are expected to play a prominent role. For the synthesis of these frequencies, the all-digital phase locked loop (ADPLL) has recently gained much attention. LÄS MER
3. Crest Factor Reduction using High Level Synthesis
Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)Sammanfattning : Modern wireless mobile communication technology has made noticeable improvements from the technologies in the past but is still plagued by poor power efficiency of power amplifiers found in today’s base stations. One of the factors that affect the power efficiency adversely comes from modern modulation techniques like orthogonal frequency division multiplexing which result in signals with high peak to average power ratio, also known as the crest factor.

4. Unmanned Aerial Vehicles Communications.
Magister-uppsats, Blekinge Tekniska Högskola/Avdelningen för signalbehandlingSammanfattning : This Project deals with a small Unmanned Aerial Vehicle (UAV)Communication system. The considered distance between UAVs is 100 m to 10 km. These small UAVs are usually used for civil purposes like fire fighting, for farmers etc. LÄS MER
