  1. 1. Performance of a Non-Orthogonal Multiple Access System with Full-duplex Relaying over Nakagami-m Fading

    University essay from Blekinge Tekniska Högskola/Fakulteten för datavetenskaper

    Author : Rahul Chowdary Erpina; Viswakanth Reddy Gopireddy; [2021]
    Keywords : NOMA; Full Duplex Relaying; Nakagami-m Fading; Power domain NOMA; Successive Interference Cancellation; Half Duplex Relaying; OFDMA; Code domain-NOMA; Time domain-NOMA.;

    Abstract : In our thesis work, we analyze the performance analysis of a power domain NonOrthogonal Multiple Access (NOMA) system in which the closer user acts as fullduplex relaying to forward the signal to farther user. Because Nakagami-m distribution is a generalized case including the two common fading distributions as specialcases: Rayleigh distribution (m=1), Rician distribution (m>1). READ MORE

  3. 2. High-Performance Wireless Communications for Smart Grids

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Konstantina Roussou; [2020]
    Keywords : ;

    Abstract : The increased energy needs of today’s society, as well as the necessity for improved and more sustainable energy management impose the transition from the traditional power grids to the smart grids. Smart grids are enabled by the advances in Information and Communication technologies and automation. READ MORE

  4. 3. FFT Implemention on FPGA for 5G Networks

    University essay from Linköpings universitet/Datorteknik

    Author : Vlad Valentin Vasilica; [2019]
    Keywords : FFT; OFDMA; Physical design; FPGA; 5G; VHDL; CP-OFDMA; Radix-2; 2048-Point;

    Abstract : The main goal of this thesis will be the design and implementation of a 2048-point FFT on an FPGA through the use of VHDL code.The FFT will use a butterfly Radix-2 architecture with focus on the comparison of the parameters between the system with different Worlengths, Coefficient Wordlengths and Symbol Error rates as well as different modulation types, comparing 64QAM and 256QAM for the 5Gsystem.

    Abstract : Long Term Evolution (LTE) known in the market as 4G LTE, it is an evolution of the GSM/UMTS standard. The overall aim of LTE was to provide a new radio access technology focusing on packet-switched data only. LTE has provided a new peak download rates, low data transfer latencies, and improved the support for mobility. READ MORE

  6. 5. Theoretical Investigation of a new OFDM Access-Network Topology (OTONES)

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

    Author : Aditya Kakkar; [2013]
