A broadband Microwave Transceiver Front-end for an Airborne Software Defined Radio Experiment
(Virginia Tech, 2015-01-26)
This document describes the design, simulation, construction, and test of a wideband analog transceiver front-end for use in an airborne software defined radio (SDR) experiment. The transceiver must operate in the GSM-1800 ...
Design of Software Defined Radio for SuperDARN Radar
(Virginia Tech, 2019)
Software defined radio (SDR) is a rapidly developing field enabled by continuing improvements in digital electronics. Software defined radio has been used extensively in communication systems due to its flexibility and ...
Software-Defined Radio Implementation of Two Physical Layer Security Techniques
(Virginia Tech, 2018-02-09)
This thesis discusses the design of two Physical Layer Security (PLS) techniques on Software Defined Radios (SDRs). PLS is a classification of security methods that take advantage of physical properties in the waveform ...
Distributed Ground Station Network for CubeSat Communications
(Virginia Tech, 2014-01-27)
In the last decade the world has seen a steadily increasing number of Cube Satellites deployed to Low Earth Orbit. Traditionally, these cubesats rely on Amateur Radio communications technology that are proven to work from ...
Design and Implementation of a Constant Envelope OFDM Waveform in a Software-Defined Radio Platform
(Virginia Tech, 2016-06-30)
This thesis examines the high peak-to-average-power ratio (PAPR) problem of OFDM and other spectrally-efficient multicarrier modulation schemes, specifically their stringent requirements for highly linear, power-inefficient ...
