  1. 1. 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

  3. 2. 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

  4. 3. On Generating Complex Numbers for FFT and NCO Using the CORDIC Algorithm

    University essay from Institutionen för systemteknik

    Author : Anton Andersson; [2008]
    Keywords : FFT; NCO; CORDIC algorithm; CORDIC convergence; CORDIC error analysis;

    Abstract : This report has been compiled to document the thesis work carried out by Anton Andersson for Coresonic AB. The task was to develop an accelerator that could generate complex numbers suitable for fast fourier transforms (FFT) and tuning the phase of complex signals (NCO). Of many ways to achieve this, the CORDIC algorithm was chosen. READ MORE

  5. 4. Sound Level Measurement System

    University essay from Institutionen för systemteknik

    Author : Tore Johansson; [2006]
    Keywords : FFT; VHDL; FPGA;

    Abstract : The purpose of this master thesis work is to design a device that measures the loudness of sound for different frequencies. This device is divided in three parts; a microphone that captures the sound, one A/D converter that samples the sound and one FPGA which analyse the data using an FFT algorithm. READ MORE

  6. 5. Improved implementation of a 1K FFT with low power consumption

    University essay from Institutionen för systemteknik

    Author : Petter Näslund; Mikael Åkesson; [2005]
    Keywords : Electronics; FFT; synthesis; low power; VHDL.; Elektronik;

    Abstract : In this master thesis, a behavioral VHDL model of a 1k Fast Fourier Transform (FFT) algorithm has been improved, first to make it synthesizable and second to obtain a low power consumption. The purpose of the thesis has not been to focus on the FFT algorithm itself or the theory behind it. READ MORE
