1. 1. 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.

3. 2. Using HLS for Acceleration of FPGA Development: A 3780-Point FFT Case Study

   University essay from Linköpings universitet/Datorteknik; Linköpings universitet/Tekniska fakulteten

   Author : Christoffer Hejdström; [2022]
   Keywords : 3780; hls; fpga;

   Abstract : Manually designing hardware for fpga implementations is time consuming. Onepossible way to accelerate the development of hardware is to use high level syn-thesis (hls) tools. Such tools synthesizes a high level model written in a languagesuch as c++ into hardware. READ MORE

4. 3. 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.

5. 4. Comparing Android Runtime with native : Fast Fourier Transform on Android

   University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

   Author : André Danielsson; [2017]
   Keywords : Android; NDK; Dalvik; Java; C ; Native; Android Runtime; Clang; Java Native Interface; Digital Signal Processing; Fast Fourier Transform; Vectorization; NEON; Performance Evaluation;

   Abstract : This thesis investigates the performance differences between Java code compiled by Android Runtime and C++ code compiled by Clang on Android. For testing the differences, the Fast Fourier Transform (FFT) algorithm was chosen to demonstrate examples of when it is relevant to have high performance computing on a mobile device. READ MORE

6. 5. Signal Processing for mmWave MIMO Radar

   University essay from Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

   Author : Óscar Faus García; [2015]
   Keywords : radar; automotive; MIMO; CW; 79 GHz; short-range radars SRR ; millimeter wave; CFAR; simulations; phase modulation; algorithms; system gain;

   Abstract : This thesis addresses the design study, implementation and analysis of signal processing algorithms for a 79 GHz millimeter-wave Phase Modulated Continuous Wave (PMCW) Multi Input Multi Output (MIMO) short range radar; performed in IMEC research institute (Leuven, Belgium). The radar system targets high resolution performance with low power consumption in order to integrate a full MIMO radar transceiver with digital processor and antennas in a compact package featuring a size of 1 cm2.
