Introduction to Digital Signal Processing (DSP) Workshop — by Karan Sajnani

Instructor: Karan Sajnani, CEO & Founder, RUDRA Cybersecurity

The Radio Hacking Kampung workshop will introduce participants to wireless communications and digital signal processing (DSP). This workshop will introduce participants to the basics of wireless technologies, specifically SDR, and the tools (hardware and software) that are typically used to capture and work with signals in the digital realm. This workshop will be in the format of a presentation with live exercises. Participants are encouraged to bring in their laptops to follow along. The workshop is beginner-friendly and will start out with basic physics behind electromagnetic waves, frequency, amplitude, phase and progress into the realm of complex numbers, DSP and modulation schemes.

This is a beginner-friendly technical workshop. This workshop will also assume that you have some basic knowledge of Python, NumPy, MatPlotLib, binary/hex, basic programming skills, Linux command line and networking. Great-to-have knowledge would be complex numbers and DSP — however, these subjects will be covered in the workshop. To get up to speed on the basics, check out the following:
