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.

Dear GNU Radio community,
due to lockdown restricted access of students to universities, I have recorded
videos for the undergraduate course on Digital Communication. 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
