  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. Efficient Energy Use of FPGA for Underwater Sensor Network

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Erik Amgård; Kevin Bergman; [2019]
    Keywords : Underwater Sensor Network; FPGA; FFT; VHDL;

    Abstract : Operational time is becoming an increasingly important aspect in electronic devices and is also highly relevant in Underwater Acoustic Sensor Networks (UWSN). This thesis contains a study which explores what can be done to de-crease power consumption while maintaining the same functionality of an FPGA inside an underwater sensor-node network. READ MORE

  4. 3. Hardware Implementation of a 32-point Radix-2 FFT Architecture

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

    Author : Ying Gao; [2015]
    Keywords : Radix- 2 FFT; Hardware Implementation; synthesis; place route; prime time; power consumption; Technology and Engineering;

    Abstract : The Fast Fourier Transform (FFT) algorithm has been widely used in the Digital Signal Processing industry as a rudimentary operation to select the specific frequency components of a signal, which has been involved with other time domain signals. In order to fulfill the requirements of executing precise calculations and less power & area consumption, an algorithm with less number of adders and multipliers is used. READ MORE

  5. 4. Implementation of 64-point FFTs as a building block for OFDM-based standards with respect to different criteria

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

    Author : Sarojanarayanamurthy Rajavari Krishnaih Lokanadhan; [2013]
    Keywords : ;

    Abstract : Abstract This master thesis implements a critical block: Fast Fourier Transform (FFT)/Inverse Fast Fourier Transform (IFFT) for standards using Orthogonal Frequency Division Multiplexing (OFDM). They are used in OFDM systems for modulating / demodulating subcarriers. READ MORE

  6. 5. Study of Interferer Canceling Systems in a Software Defined Radio Receiver

    University essay from Institutionen för systemteknik; Tekniska högskolan

    Author : Oskar Holstensson; [2013]
    Keywords : ASIC; FFT; Interferer Cancellation; RF; SDR; VHDL;

    Abstract : This thesis describes the work related to an interferer rejection system employing frequency analysis and cancellation through phase-opposed signal injection. The first device in the frequency analysis chain, an analog fast Fourier transform application-specific integrated circuit (ASIC), was improved upon. READ MORE
