  1. 1. One Million-Point FFT

    Master-uppsats, Linköpings universitet/Datorteknik

    Författare :Tobias Mellqvist; Hans Kanders; [2018]
    Nyckelord :Large FFT; FFT; Cooley–Tukey; SDF; Binary tree; FPGA; triangular matrix;

    Sammanfattning : The goal of this thesis has been to implement a hardware architecture for FPGA that calculates the fast Fourier transform (FFT) of a signal using one million samples. The FFT has been designed using a single-delay feedback architecture withrotators and butterflies, including a three-stage rotator with one million rotation angles. LÄS MER

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

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

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

    Sammanfattning : 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. LÄS MER

  7. 5. VHDL Implementation of Flexible Frequency-Band Reallocation (FFBR) Network

    Master-uppsats, Institutionen för systemteknik

    Författare :Abrar Hussain Shahid; [2011]
    Nyckelord :20-channel FFBR network; 20-point FFT IFFT; complex multiplier; polyphase components; radix-2; radix-5;

    Sammanfattning : In digital communication systems, satellites give us world wide services. These satellites should effectively use the available bounded frequency spectrum and, therefore, to carry out flexible frequency-band reallocation (FFBR), on-board signal processing implementation on FFBR network is needed.
