4c986a70a4 Really fix the SBS-1 pruning issue this time. 2012-10-29 09:42:28 -07:00
Johnathan Corgan
7ad09f5b14 Added option for pulse matched filtering 
Pulse matched filtering places a boxcar filter upstream of the
averager and preamble detector.  The filter length is equivalent
to the number of samples in one Mode S chip (0.5us).  This
technique enhances operation when using sample rates > 4Msps.

When using --pmf, the threshold may need to be reduced a dB or
two from what would have been optimal without --pmf.

* rx_path.py now takes 'use_pmf', defaults to False

* modes_rx has new CLI option '-p' or '--pmf' to turn on PMF

* modes_gui has new checkbox on Setup tab

a3f2dec1f9 CPR decoder: Keep a separate list for sfc and air positions to keep them from stepping on each other. 2012-10-17 09:24:15 -07:00

0b30db353d CPR: surface decoding still exhibits occasional errors when m~=0. Suspect it might actually be a bug in the encoder. 2012-10-17 09:13:10 -07:00

132edc9148 Add 'make uninstall' to cmake build 
This commit adds the ability to uninstall gr-air-modes safely,
without having to manually delete the installation files.

62304ff59e Refactor flowgraph into hierarchical block 
This commit creates air_modes.rx_path, which is the common portion
of the flowgraph once the sample source and possible resampler are
created.  It takes baseband I/Q and emits Mode-S packets into the
supplied message queue.

85da74b43a Fix preamble/slicer dB numbers. Was using power ratios for voltages (2.0 instead of 1.414 for 3dB, etc.). No real performance change. 
Fix suggested by Denis Gapotchenko.

f1a5c676b7 Fixed erroneous include dir variable 
FindGnuradioCore was only working if GNU Radio was installed in
typical paths, since the pkg-config variable was wrong.

This was fixed in GNU Radio HOWTO a while back.
