DSP for SDR

The barrier to entry in software-defined radio is now almost non-existent. Wide band, receive-only hardware can be obtained for as little as $10, and tools like gqrx and SDR# make it extremely easy to get started listening to signals. However, there is a steep learning curve graduating from an SDR script kiddie to developing your own SDR tools. In this talk, I’ll cover the basic theory behind software-defined radios digital signal processing, and digital communication, including I/Q samples, FIR filters, timing and carrier recovery, and more.
