I am quite interested in the ATSC project due to some previous HDTV R&D experience.
I am not quite sure about the current status of this project.
According to my understanding, ATSC has a very high throughput requirement with a symbol rate=10.72M / sec
Considering this high symbol rate and the computationally intense algorithm in RS decoder, Equalizer, Viterbi, etc., I am just wondering how powerful the computer has to be to process all these in realtime?
What kind of computers have been used in the gr-atsc project to process realtime HDTV?
Recalling that a PC do not have the luxury of parallel computation.
For instance, a 4.0G CPU has to process one symbol in 400 clock durations, which seems to be not enough.
Thanks
