1. 1. Quantum Annealing Algorithms for PAPR Minimisation in Wireless Networks

   University essay from Uppsala universitet/Materialteori

   Author : David Bern; [2022]
   Keywords : Quantum Mechanics; Algorithms; Quantum Annealing; Graph representation;

   Abstract : 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.

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Himanshu Gaur; Md Zahidul Islam Shahin; [2018]
   Keywords : Technology and Engineering;

   Abstract : 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. READ MORE

5. 4. An efficient Hardware implementation of the Peak Cancellation Crest Factor Reduction Algorithm

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Matteo Bernini; [2016]
   Keywords : CFR; PC-CFR; PAPR Reduction; OFDM; CFR; PC-CFR; PAPR Reduction; OFDM;

   Abstract : 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. READ MORE

6. 5. Modeling in Simulink and Synthesis of Digital Pre-Distortion for WLAN Power Amplifiers on a Coarse-Grained Reconfigurable Fabric

   University essay from Linköpings universitet/Elektroniska Kretsar och System

   Author : Muhammad Safdar; [2016]
   Keywords : ;

   Abstract : 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. READ MORE
