1. Approximation of General Semi-Markov Models Using Expolynomials
Master-uppsats, KTH/Matematisk statistikSammanfattning : Safety analysis is critical when developing new engineering systems. Many systems have to function under randomly occurring events, making stochastic processes useful in a safety modelling context. However, a general stochastic process is very challenging to analyse mathematically. LÄS MER
2. Machine Learning for PAPR Distortion Reduction in OFDM Systems
Master-uppsats, KTH/SignalbehandlingSammanfattning : The purpose of the project is to investigate the possibility of using modern machine learning to model nonlinear analog devices like the Power Amplifier (PA), and study the feasibility of using such models in wireless systems design. Orthogonal frequency division multiplexing (OFDM) is one of the most prominent modulation technique used in several standards like 802. LÄS MER
3. Digital Predistortion for Broadcast FM repeaters
Uppsats för yrkesexamina på avancerad nivå, KTH/SignalbehandlingSammanfattning : This thesis presents the design and implementation of a memoryless and adaptive digital predistorter used to linearize a power amplier. Specically, it deals with the implementation of a so-called constantgain predistorter, based on a lookup table, on a digital signal processing board built around an FPGA. LÄS MER
4. Model-based pre-distortion for Signal Generators
Magister-uppsats, Institutionen för teknik och byggd miljöSammanfattning : Spectrally pure signals are an indispensable requirement when the Signal Generator (SG) is to be used as part of a test bed. However, even sophisticated equipment may not comply with the needs imposed by certain applications. LÄS MER
