So I've been reading about the new OTFS wireless signal modulation that's aimed at cellular 6G to replace OFDM. Kinda neat that the new modulation scheme has better immunity against time-based distortions like the doppler effect and immunity against signal reflections and back-scatter. It appears to be aimed at high-bandwidth applications instead of long-range like LoRa

...but I was thinking, it would be possible to use the chirp modulation within the delay-doppler domain. Enter "Chirp Delay-Doppler Domain Modulation" Seems exciting but I never graduated high-school so it's above my head quite a bit. There are some papers about it online. I kinda want to try it with GNU radio just for fun
