GNU Radio is a framework to implement software-defined radio applications on standard PC hardware, embedded systems (from handheld spectrum analyzers to Raspberry Pis) to servers. This talk will take the surprise out of how to implement a very simple transmitter and a matching receiver application, where to go from there, how to improve upon existing designs, and address common pitfalls.

The audience will be introduced to the flowgraph as a means of describing a signal processing application, to core GNU Radio concepts, important design patterns, and how they interact with common communications engineering approaches. As a prerequisite for following the talk, you should be familiar with the basics of signals. An understanding of complex baseband and IQ signals will enhance the value of the talk to the reader, but is not strictly necessary.

To (optionally) replicate the examples shown, a computer running a recent version of Windows, Linux, or Mac OS on which the user is able to install software is required.
