Satellite typically doesn't use cdma. See dvb-s

  There's no reason to assume starlink works like a typical satellite, though. Digital video broadcast in particular is in one direction from geostationary orbit. Latency is on the order of several seconds due to all the forward error correction that's necessary to tolerate bit errors in reception. There's not really any need for a "multiple access" scheme because "channels" are statically allocated frequency bands. I would think the radio technology in starlink should more closely resemble modern LTE and 5G cell networks, whether you want to call that CDMA, OFDM, or whatever the specific techniques these days are called.

    > There's no reason to assume starlink works like a typical satellite, though. And it does not. Starlink satellites do active switching unlike BSS satellites which only transmodulate and redirect.

      Not true. Most modern geo satellites for internet have switching capabilities.

    Satellites are interference limited and power limited. Dbv is not just for broadcasting, despite its name. It's used for pretty much all non-proprietary satellite waveforms.
