Remote Triggered Software Defined Radio Using GNU Radio

Abstract

Software-defined radio (SDR), refers to wireless communication in which the transmitter and receiver both are able to modulate signals defined by a computer software. It is the capability of a system to behave as a transceiver and to be configured to various systems with the help data flow graphs on a software. Software Defined Radio is mainly configured by a popular open source library – GNU Radio. With the increasing need of laboratories and requirements of multiple devices, colleges and universities are unable to supplement to the demands of the students limiting them from performing experiments. In the same way, Software Defined Radio devices are high cost equipment not affordable by every college. This increasing demand in Software Defined Radio technology calls for finding an optimal solution to the problem. The solution involves, bringing Software Defined Radio - GNU Radio Library to a remote platform using Cloud Computing, Virtual Network Computing and Web Technologies, wherein the user is able to create data flow graphs and run his experiments on the hardware connected to the servers from anywhere across the globe. The benefits of using this Remote Software Defined Radio platform would be providing hardware access to every user without the need of purchasing it and eventually to provide a remote learning experience for the user. This would also mean that colleges can get access to readily available hardware in no time without setting up an actual laboratory.
