-Decoding ATSC using 6.4MSps rate
----------------------------------
-
-1) Verify signal, adjust antenna and find best gain setting using uhd_fft.py,
-station frequency from the fcc video database, and sample rate to 6.4e6.
-
-2) Capture data - adjust gain (-g) frequency (-f) and which side
-the daughterboard is on to fit your local setup:
-
-uhd_rx_cfile.py -s --samp-rate=6.4e6 -g 65 -f 503e6 atsc_data_6-4m_complex
-
-You probably still need fast disks to take the data, like a raid-0 set of
-striped sata drives. Make sure there are no or very few Ou overruns. Saving
-the raw usrp data in 'short' form halves the disk space/bus bandwidth that
-the usual complex form uses.
-
-3) Run atsc_rx.py:
-
-./atsc_rx.py atsc_data_6-4m_complex outfile.ts

-# This module starts the atsc processing chain taking the captured
-# off-air signal created with:
-#
-#  uhd_rx_cfile.py  --samp-rate=6.4e6
-#                   -f <center of tv signal channel freq>
-#                   -g <appropriate gain for best signal / noise>
-#                   -s output shorts
-#
-# This python script converts from interleaved shorts to the complex data type,
-# then multiplies the sample rate by 3, from 6.4e6 to 19.2e6
-# complex samples / sec, then lowpass filters with a cutoff of 3.2MHz
-# and a transition band width of .5MHz.  Center of the tv channels is
-# now at 0 with edges at -3.2MHz and 3.2MHz. This puts the pilot at
-# -3MHz + 309KHz. Next a root raised cosine filter is aplied to match the one
-# in the transmitter and thus reduce ISI. The phased locked loop then locks to
-# the pilot and outputs just the real part of the signal ( as information is
-# not stored in the phase with atsc ), this is then feed to the bit lock
-# loop, this looks for the bit sync marker put at the beginning of every segment
-# field, this then adjusts the timing so the amplitude will be sampled at the
-# correct sample ( sub-sample is used in this case ).
-#
-# Output is float.
