  1. 1. Evaluating GPU for Radio Algorithms : Assessing Performance and Power Consumption of GPUs in Wireless Radio Communication Systems

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Albin André; [2023]
    Nyckelord :GPU; CUDA; Signal Processing; Radio; Algorithms; GPU; CUDA; Signalbehandling; Radio; Algoritmer;

    Sammanfattning : This thesis evaluates the viability of a Graphics Processing Unit (GPU) in tasks of signal processing associated with radio base stations in cellular networks. The development of Application Specific Integrated Circuits (ASICs) is lengthy and highly expensive, but they are efficient in terms of power consumption. LÄS MER

  3. 2. 64-point FFT Instruction Implementation and Evaluation on a Microcode Programmable Processor

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik; Linköpings universitet/Tekniska fakulteten

    Författare :Yongjun Liu; Zejun Huang; [2022]
    Nyckelord :FFT; Instruction design;

    Sammanfattning : Fast Fourier Transform is an efficient algorithm for computing the Discrete Fourier Transform (DFT) and one of the most important algorithms used in many digital signal processing applications over decades. This thesis presents an efficient implementation method of a 32-bit complex number 64-point FFT instruction on a micro-programmable processor. LÄS MER

  4. 3. Arbitrary Decimation for High Sample Rates, Algorithm Design and FPGA implementation

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

    Författare :Fredrik Peterson; [2019]
    Nyckelord :Sample Rate Conversion; Decimation; Farrow Structure; Farrow Filter; Technology and Engineering;

    Sammanfattning : This master thesis investigates how to perform irrational decimation, the process of reducing the sample rate of a signal, for high throughput systems. The thesis work consists both an algorithmic part and an implementation part. LÄS MER

  5. 4. Make it Simpler : Structure-aware mesh decimation of large scale models

    Master-uppsats, Linköpings universitet/Informationskodning

    Författare :Daniel Böök; [2019]
    Nyckelord :mesh decimation; structure-aware;

    Sammanfattning : A 3D-model consists out of triangles, and in many cases, the amount of triangles are unnecessarily large for the application of the model. If the camera is far away from a model, why should all triangles be there when in reality it would make sense to only show the contour of the model? Mesh decimation is often used to solve this problem, and its goal is to minimize the amount of triangles while still keep the visual representation intact. LÄS MER

  7. 5. Analysis of forklift data – A process for decimating data and analyzing fork positioning functions

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Gustav Sternelöv; [2017]
    Nyckelord :Statistics; CAN data; autoregressive; AR; decimation; signal processing; bayesian hierarchical model;

    Sammanfattning : Investigated in this thesis are the possibilities and effects of reducing CAN data collected from forklifts. The purpose of reducing the data was to create the possibility of exporting and managing data for multiple forklifts and a relatively long period of time. LÄS MER
