1. Quantum Annealing Algorithms for PAPR Minimisation in Wireless Networks
Master-uppsats, Uppsala universitet/MaterialteoriSammanfattning : In this thesis, we devise a scheme to run PAPR minimisation with 3GPP EVM requirement as constraint on the D-Wave Systems’ quantum annealer. The PAPR minimisation is a problem central to optimising the costs and performance of wireless networks becoming increasingly difficult for larger OFDM-MIMO systems, while the EVM constraint needs to be satisfied to reach an industry standard performance.

2. Reduction of Crosstalk Distortion in 5G
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : Increasing demand for higher data rates in wireless communication systems has tremendously evolved over the last years. This demand is rapidly increasing with rising in number of wireless devices. LÄS MER
3. Efficient DPD Coefficient Extraction For Compensating Antenna Crosstalk And Mismatch Effects In Advanced Antenna System
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : The demand for high data rates in a wireless communication system has experienced a remarkable growth over the last years. This demand is continually increasing with the growing number of wirelessly connected devices. Thus, there is a continuing hunt for increasing the data transmission rate in wireless communication systems. LÄS MER
4. An efficient Hardware implementation of the Peak Cancellation Crest Factor Reduction Algorithm
Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)Sammanfattning : An important component of the cost of a radio base station comes from to the Power Amplifier driving the array of antennas. The cost can be split in Capital and Operational expenditure, due to the high design and realization costs and low energy efficiency of the Power Amplifier respectively. LÄS MER
5. Modeling in Simulink and Synthesis of Digital Pre-Distortion for WLAN Power Amplifiers on a Coarse-Grained Reconfigurable Fabric
Master-uppsats, Linköpings universitet/Elektroniska Kretsar och SystemSammanfattning : High data rates are highly demanded now-a-days in most of the communication systems such as audio/video broadcasting, cable networks, wireless networks etc. This can be achieved using Orthogonal Frequency Division Multiplexing (OFDM), which is a bandwidth-efficient method.
