Talk: Software Defined Radio (SDR) technology replaces the traditional radio hardware systems with hardware and software that uses Digital Signal Processing techniques to both transmit and receive radio signals. In the past, SDR technology was primarily used for complex military radio and radar systems, but with the advent of cellular phones and the high-volume RF components used in them, the technique is now in widespread use. Today, inexpensive ($20) USB dongles, designed to receive the DVB digital TV video broadcast signals, incorporate a front end receiver and an In-Phase and Quadrature Analog to digital converter. When used with a laptop, DVB-USB dongles utilize SDR to implement a wide range of products. Tom will discuss some of the theory and will demonstrate available open-source software that runs on laptops, phones, and even small-systems like the RaspberryPi allowing you to experiment with SDR. He will show how you can develop your own radio receivers using Gnu Radio Companion -- a graphical drag-and-drop front end to SDR systems. Also radio direction finding work being done with UW students will be presented. Are you using SDR in your systems today? Bring them for show-and-tell!
