In this tutorial we will present the fundamental theory behind the design of a generic PHY layer software defined radio (SDR) and demonstrate the first principles implementation, design and real time operation of an SDR using off-the-air signal live in the tutorial. We will use the $20 RTL-SDR USB device which can produce 8 bit I/Q samples at up to 2.8MHz sampling rate and receive over the range 50MHz to almost 1.7GHz. As part of the tutorial we will build a first SDR implemented AM and then FM radio receiver, followed by implementations and demonstrations of 433MHz and 868MHz digital QAM receivers. We will also viewing some other signals around us (from IoT temperature sensors, mobile/wireless and so on). We will view all signals and build all components and designs from first principles DSP theory using MATLAB/Simulink and run real time on a standard Windows PC hosting MATLAB and drivers for the RTL-SDR. Attendees will receive a free USB RTL-SDR stick and access to all presented materials, instruction in, and use of full MATLAB/Simulink desktop and course notes including open versions of all of the SDR designs (and more) that were presented.
