1. 1. Integrated Sensing and Communicationusing OFDM and Stepped FMCWSignals : Proof-of-Concept and Evaluation with Software DefinedRadios

   University essay from Blekinge Tekniska Högskola/Fakulteten för datavetenskaper

   Author : Sai Chetan Poluri; Tejaswi Dunuka; [2023]
   Keywords : 5G and 6G Communications; FMCW; GNU Radio; ISAC; OFDM; SDR; Sensing; JSAC;

   Abstract : The thesis work shows the implementation of sensing and communication, so a basic knowledge of analog and digital communication systems is needed to understand this paper Background. With the increase in smart devices, the bandwidth requirements are increased, which created congestion in the radio spectrum resources. READ MORE

3. 2. Latency Bounds for Memory-Based FFTs with Applications in OFDM Communication

   University essay from Linköpings universitet/Institutionen för systemteknik

   Author : Xiangbin Tan; Tadesse Hadush Negash; [2023]
   Keywords : FFT; scheduling; memory-based architecture; latency;

   Abstract : Future communication systems require low latency Fast Fourier transform (FFT)computation with a small cost of area. In this study, a memory-based FFT processorwith low latency is designed. READ MORE

4. 3. 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.

5. 4. Importance Sampling in Wireless Communication Systems with Ultra-Low Error Rates

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

   Author : Bharat Maheshwari; Yewen Zhou; [2022]
   Keywords : error region; Monte Carlo; importance sampling; rejection sampling; Kullback-Leibler divergence.; Technology and Engineering;

   Abstract : Simulation mimics the behaviour of real world processes or the system over time. It helps us to understand the impact of modification and the effect of introducing various interventions to a system. READ MORE

6. 5. Overcoming Inter-carrier-interference in OFDM System

   University essay from Linköpings universitet/Kommunikationssystem

   Author : Fukang Guo; Luoan Lu; [2021]
   Keywords : ICI; OFDM; TDCP; FDCE; Windowing-OFDM; 5G;

   Abstract : This master thesis aims for Inter-carrier interference (ICI) mitigation in orthogonal frequency division multiplexing (OFDM) system by considering designs of frequency domain cyclic extension(FDCE) and optimal windowing pulse shape. Although OFDM system has been put forward in the 1970s, it has just emerged in 4G. READ MORE
