This is so sick! How'd you manage to get the specs for CDMA? Did you reverse engineer?
The specs are public from 3gpp2 (https://www.3gpp2.org/). I didn't have to reverse engineer but in the initial RF bringup, even with the specs, it took me a while and had to pick up some old CDMA test equipment to capture actual BTS signals to help me understand it better.
