== NAME
|
||
|
|
|
||
|
|
fst4sim, qra64sim - Generate simulated QRA64, FST4, and FST4W mode signals.
|
||
|
|
|
||
|
|
== SYNOPSIS
|
||
|
|
|
||
|
|
*qra64sim* msg A-E Nsigs fDop DT Nfiles SNR
|
||
|
|
|
||

|
||
|
|
|
||
|
|
== DESCRIPTION
|
||
|
|
|
||
|
|
*fst4sim* can be used to generate FST4 and FST4W signals with
|
||
|
|
user-specified message content, mode parameters, and SNR values.
|
||
|
|
|
||
|
|
== ARGS
|
||
|
|
|
||
|
|
*msg*::
|
||
|
|
|
||
|
|
A valid QRA64, FST4, or FST4W message enclosed in quotation marks.
|
||
|
|
|
||
|
|
*A-E*::
|
||
|
|
|
||
|
|
QRA64 sub-mode designator.
|
||
|
|
|
||
|
|
*Nsigs*::
|
||
|
|
|
||
|
|
Number of signals to simulate, distributed even across a 2000 Hz
|
||
|
|
bandwidth.
|
||
|
|
|
||
|
|
*TRsec*::
|
||
|
|
|
||
|
|
A valid T/R period duration (s).
|
||
|
|
|
||
|
|
*f0*::
|
||
|
|
|
||
|
|
Integer signal frequency offset (Hz).
|
||
|
|
|
||
|
|
*DT*::
|
||
|
|
|
||
|
|
Decimal signal time offset (s).
|
||
|
|
|
||
|
|
*h*::
|
||
|
|
|
||
|
|
A valid modulation index.
|
||
|
|
|
||
|
|
*fDop*::
|
||
|
|
|
||
|
|
Decimal Doppler frequency spread (Hz).
|
||
|
|
|
||
|
|
*del*::
|
||
|
|
|
||
|
|
Decimal Watterson model delay (ms).
|
||
|
|
|
||
|
|
*nfiles*::
|
||
|
|
|
||
|
|
Number of files to generate.
|
||
|
|
|
||
|
|
*snr*::
|
||
|
|
|
||
|
|
Add Guassian noise to simulate SNR in 2500 Hz bandwidth.
|
||
|
|
|
||
|
|
*W*::
|
||
|
|
|
||
|
|
Hint to break ties between ambiguous messages '0' as 77-bit (FST4),
|
||
|
|
'1' as 50-bit (FST4W).
|
||
|
|
|
||
|
|
Generated files are 12000 Hz sample rate, 16-bit unsigned format, mono
|
||
|
|
PCM .WAV files suitable for replay using WSJT-X either vie the GUI
|
||
|
|
*wsjtx*(1) or using the command line slow mode decoder *jt9*(1). Files
|
||
|
|
are named 000000_nnnnnn.wav (000000_nnnn.wav for QRA64), where
|
||
|
|
'nnnnnn' or 'nnnn' increments from zero.
