The world of signals fascinates many in the Security domain. The reason being it is neither visible nor tangible and the techniques of Signal Processing are highly mathematical. Signal Processing is an important part when it comes to security assessment and evaluation of modern communication systems.
GNURadio is such a powerful tool for Signal Processing and implementing software defined radios. It is open source and one can develop signal processing modules in Python or on GUI Interface easily to either simulate or work with Radio hardwares. This workshop provides a step-by-step hands-on tutorial for Signal Processing using GNUradio withhardwarelike RTL-SDR, HackRF and Ettus USRP.
