  1. 6. Latency Bounds for Memory-Based FFTs with Applications in OFDM Communication

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Xiangbin Tan; Tadesse Hadush Negash; [2023]
    Keywords : FFT; scheduling; memory-based architecture; latency;

    Abstract : Future communication systems require low latency Fast Fourier transform (FFT)computation with a small cost of area. In this study, a memory-based FFT processorwith low latency is designed. READ MORE

  6. 10. Improving the Accuracy of FFT-based GPGPU Ocean Surface Simulations

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Jacob Eriksson; Joakim Wingård; [2022-12-01]
    Keywords : computer graphics; 3D graphics; real-time rendering; Fourier transform; FFT; simulation; GPGPU; interactive; ocean wave spectrum; oceanography;

    Abstract : In this paper, we explore how the current state of the art in real-time ocean simulations can be improved in terms of simulation accuracy, while preserving performance. Current methods, both in academia and in the industry, simulate an ocean model in frequency space on the GPU, convert said model on an approximately frame-byframe basis to the spatial domain using the Fourier transform, and then read back the resulting heightfield to the CPU as input to the application’s physics engine.
