Design And Implementation Of Digital Signal Processing Hardware For A Software Radio Reciever, Jake Talbot
Design And Implementation Of Digital Signal Processing Hardware For A Software Radio Reciever, Jake Talbot
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This project summarizes the design and implementation of field programmable gate array (FPGA) based digital signal processing (DSP) hardware meant to be used in a software radio system. The filters and processing were first designed in MATLAB and then implemented using very high speed integrated circuit hardware description language (VHDL). Since this hardware is meant for a software radio system, making the hardware flexible was the main design goal. Flexibility in the FPGA design was reached using VHDL generics and generate for loops. The hardware was verified using MATLAB generated signals as stimulus to the VHDL design and comparing the …

Digital Signal Processing Techniques For Coherent Optical Communication, Gilad Goldfarb
Electronic Theses and Dissertations
Coherent detection with subsequent digital signal processing (DSP) is developed, analyzed theoretically and numerically and experimentally demonstrated in various fiber-optic transmission scenarios. The use of DSP in conjunction with coherent detection unleashes the benefits of coherent detection which rely on the preservation of full information of the incoming field. These benefits include high receiver sensitivity, the ability to achieve high spectral-efficiency and the use of advanced modulation formats. With the immense advancements in DSP speeds, many of the problems hindering the use of coherent detection in optical transmission systems have been eliminated. Most notably, DSP alleviates the need for hardware …
