Well in theory CDMA would allow two stations to broadcast on the same channel/frequency, but then each station would get exactly half the datarate minus coding overhead (9 Mbit/s rather than the current ~19). You would gain little by this change.
You're better off sticking with the current ATSC and multiplexing. Maybe move from 8VSB to 16VSB to double the datarate, but at the cost of noise like rainclouds or microwaves disrupting reception twice as often.LETTER
(short and to the point, so it gets read by my busy Employee in congress):
(1) Don't take away my TV channels 25 through 51, and sell them off to cellphone or broadband monopolies. I love getting approximately forty FREE channels, and not having to waste ~$80 a month paying the ____s over at Comcast or Verizon. The idiotic FCC plan to sell 25-51 would leave me with about 1/4 as many channels as I have now. Not acceptable.
(2) Save the internet. Google and Verizon have an agreement on how to manage Internet traffic, which will favor their services while blocking/slowing down competitive services (example: yahoo.com). Unacceptable. Support net neutrality, regulated by the FCC, the same way they regulate the Telephone monopolies (so-called common carriers).
