  1. 1. 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.

  3. 2. Designing of LTE-Advanced Downlink Transceiver on a Physical Layer

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Samiallah Shahid; Saqib Mohammad; [2013]
    Keywords : LTE-Advanced; Downlink; Transceiver; Physical Layer;

    Abstract : The evolved version of LTE is LTE-Advanced which is being developed by 3GPP. LTE-Advanced will meet or go beyond the requirements of the International Telecommunication Union (ITU) for the fourth generation (4G) radio communication standard known as IMT-Advanced. LTEAdvanced is primarily considered as a part of Release 10 of 3GPP specifications. READ MORE

  4. 3. A distributed, load-aware, power and frequency bargaining protocol for LTE-based networks

    University essay from Kommunikations- och transportsystem; Tekniska högskolan

    Author : Muhammad Sajid; Imran Siddiqui; [2012]
    Keywords : LTE; OFDMA; FFR; protocol; power allocation; frequency allocation.;

    Abstract : In this thesis a distributed, dynamic, load aware, joint power and frequency allocation protocol for 4G networks along with system-level simulated results are presented. In all cellular networks, a key limiting factor for throughput is inter-cell interference, especially at the cell edges. READ MORE

  5. 4. Analysis of LTE Radio Frame by eliminating Cyclic Prefix in OFDM and comparison of QAM and Offset-QAM

    University essay from Institutionen för datavetenskap, fysik och matematik, DFM

    Keywords : OFDM; LTE; OQAM; QAM; FBMC; FIlter Bank Multicarriers;

    Abstract : Spectral efficiency is the key factor for the development of future wireless communications. Orthogonal Frequency Division Multiple Access (OFDMA) is the multiple access technology used at physical layer of latest wireless communication technologies. READ MORE

  6. 5. A COMPARATIVE STUDY OF UMTS/WCDMA AND WIMAX TECHNOLOGIES

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : ARIF HUSSAIN; MUHAMMAD-UMAIR ASLAM; SALA HUDDIN; [2009]
    Keywords : UMTS; WCDMA; WIMAX; OFDMA; SER;

    Abstract : The field of mobile broadband in wireless communication systems is increasingly facing the challenges of the provision of high data rates, improved seamless connectivity and broadband internet services. UMTS/WCDMDA which is a third generation wireless mobile cellular technology has been adopted in most parts of the world and now undergoing a phase of evolution and will be emerged soon as LTE.
