  1. 1. Analysing Memory Performance when computing DFTs using FFTW

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

    Author : Andreas Heiskanen; Erik Johansson; [2018]
    Keywords : fftw; discrete fourier transform; fast fourier transform; hpc; perf; cache; memory analysis;

    Abstract : Discrete Fourier Transforms (DFTs) are used in a wide variety of dif-ferent scientific areas. In addition, there is an ever increasing demand on fast and effective ways of computing DFT problems with large data sets. The FFTW library is one of the most common used libraries when computing DFTs. READ MORE

  2. 2. Implementation of LTE Baseband Algorithms for a Highly Parallel DSP Platform

    University essay from Linköpings universitet/Datorteknik

    Author : Markus Keller; [2016]
    Keywords : SIMD; DSP; FFT; DFT; LTE; OFDM; ePUMA; sleipnir; Cooley Tukey; Zeroforcing; Channel equalization;

    Abstract : The division of computer engineering at Linköping’s university is currentlydeveloping an innovative parallel DSP processor architecture called ePUMA. Onepossible future purpose of the ePUMA that has been thought of is to implement itin base stations for mobile communication. READ MORE

  3. 3. Implementation and Evaluation of Spectral Subtraction with Minimum Statistics using WOLA and FFT Modulated Filter Banks

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling; Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Peddi Srinivas Rao; Vallabhaneni Sreelatha; [2014]
    Keywords : Speech Enhancement; Filter Bank; Spectral Subtraction; Wiener Filtering; PESQ; DFT ; Master of Science Programme in Electrical Engineering with emphasis on Signal Processing Masterprogram i Elektroteknik med inriktning mot signalbehandling;

    Abstract : In communication system environment speech signal is corrupted due to presence of additive acoustic noise, so with this distortion the effective communication is degraded in terms of the quality and intelligibility of speech. Now present research is going how effectively acoustic noise can be eliminated without affecting the original speech quality, this tends to be our challenging in this current research thesis work.

  4. 4. Benchmarking of Sleipnir DSP Processor, ePUMA Platform

    University essay from Linköpings universitet/Linköpings universitet/DatorteknikTekniska högskolan

    Author : Somasekar Murugesan; [2011]
    Keywords : Benchmarking; DSP Processor; Sleipnir core; Digital Signal Processing; FFT; DFT; DWT; DCT; FIR; assembler; ePUMA;

    Abstract : Choosing a right processor for an embedded application, or designing a new pro-cessor requires us to know how it stacks up against the competition, or sellinga processor requires a credible communication about its performance to the cus-tomers, which means benchmarking of a processor is very important. They arerecognized world wide by processor vendors and customers alike as the fact-basedway to evaluate and communicate embedded processor performance. READ MORE

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

    University essay from Linköpings universitet/Institutionen för systemteknik

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

    Abstract : 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.
