NAME

       fdmdv_demod  - a diagnostic tool for the codec2 library to create a codec2 bit file from a
       series of FDMDV modem samples.

SYNOPSIS

       fdmdv_demod usage: InputModemRawFile OutputBitFile [Nc] [OctaveDumpFile]

DESCRIPTION

       Given an input raw file (8kHz, 16 bit shorts) of FDMDV modem samples  outputs  a  file  of
       bits.   The  output  file  is  assumed to be arranged as codec frames of 56 bits (7 bytes)
       which are received as two 28 bit modem frames.

       Demod states can be optionally logged to an Octave  file  for  display  using  the  Octave
       script fdmdv_demod_c.m.  This is useful for checking demod performance.

EXAMPLE

        fdmdv_dmod hts1a_fdmdv.raw hts1a.c2

OPTIONS

       The first argument, InputModemRawFile is the file name of a file with FDMDV modem samples.
       If "-" is given the input is taken from stdin.

       The second argument, OutputBitFile is the file name of a file to be  created  with  codec2
       bits. If "-" is given the output is sent to stdout.

       The  optional  third  argument,  [Nc]  is  the number of carriers to use in the modem. The
       default is 14.  The minimum is 2 and the maximum is 20.

       The optional fourth argument, [OctaveDumpFile] is the name  of  to  Octave  data  file  to
       create.
