Did you ever design a real-world over-the-air communication system?

Does studying digital communications make you tired of simulations?

Do you want to get your hands on real-world OFDM communications?

Use a cheap soundcard as the radio!

A closed control loop adjusts the synchronization point of the OFDM system.

With a cheap sound card, speakers and a microphone, you have all the hardware you need to run your own real-world wireless communication experiments. In addition, you can literally hear your system work!

Here, at DSPIllustrations.com we have developed a tutorial using Jupyter notebooks on building your own OFDM physical layer. In particular, the course covers the following aspects:

Up- and Downconversion

Fundamentals of OFDM modulation and demodulation

The Schmidl-Cox metric for time synchronization and frequency offset estimation

OFDM Channel Estimation

OFDM Channel Equalization

5G waveforms: Filtered OFDM (F-OFDM)

The tutorial focuses on practical aspects and real-world experiments rather than on mathematical derivations. So, it's the perfect complement to your theoretical studies!

Using an audio cable, the system can even reach 256QAM modulation.
