I've uploaded a sample of ATSC signal here:
http://dl.dropbox.com/u/63648777/atsc_data_6m4_short.bz2
The format is interleaved shorts at 6.4 MS like the current ATSC code uses. I
successfully decoded this data with gnuradio, so the receiver code does work.
Here's how I see the signal flow through the first part of the receiver:
input from usrp or file
(6.4MS complex short)
filter and translate
(19.2MS real float)
fpll
(19.2MS real float)
bit_timing_loop
(~10.76MS real float) [+ other data?]
field sync recovery
