I too thought this was very generous and thank the OP.. Despite being in industry for over 25 years, I always enjoy these types of presentations, as there seems to be something new to learn.

As I try to illustrate most concepts of discrete time digital signal processing with GNU Radio (and GNU/Octave when needed for post-processing), I thought this community might be interested. Please remember that as a physicist by training, I have no basic knowledge on digital communication or SDR other than my own experience, so some topics might be either wrong or misrepresented, or both. This year's work has been to shift all (most ?) slides and demonstrations to GNU Radio 3.8. Feedback, comments and error reports are of course welcome. All videos are at http://jmfriedt.free.fr/ under "Licence 3 EEA" (bachelor degree -- electronics engineering): http://jmfriedt.free.fr/TI2020_1.mp4 (1.5 h) -- Introduction, hardware, AM (aeronautical communication) http://jmfriedt.free.fr/TI2020_2.mp4 (1.5 h) -- Modulations (FM, PM) -- application to broadcast commercial FM and NOAA LEO satellite reception http://jmfriedt.free.fr/TI2020_3.mp4 (1.0 h) -- Division Multiple Access, application to receiving multiple FM stations and POCSAG decoding using external software http://jmfriedt.free.fr/TI2020_4.mp4 (1.43 h) -- CDMA and GPS decoding. I forgot to mention the link http://jmfriedt.org/gps/gps_lab.tar.gz with datasets collected with a RTL-SDR DVB-T dongle at 1.57542 GHz carrier frequency and a rate of 1.023 MS/s fitted with an active GPS antenna polarized by a 5-V bias T. http://jmfriedt.free.fr/TI2020_5.mp4 (45 min) -- pulse compression and link budget http://jmfriedt.free.fr/TI2020_6.mp4 (1h40) -- antenna basics http://jmfriedt.free.fr/TI2020_7.mp4 (45 min) -- channel capacity, Shannon theorem http://jmfriedt.free.fr/TI2020_8.mp4 (1h40) -- synchronization and digital processing of radiofrequency signals Hoping that someone might find these useful and provide feedback, best, JM
