77d695f2ef First stab at interrogation uplink processing. Getting bits, inefficiently. 2013-08-09 21:10:02 -07:00

a528f375f7 Huge messy reorg to move things into the GR3.7 paradigm. Mostly in effort to get 
SWIG magic to work on member functions. Can change sample rate on the fly now.

d84c0c3204 Parser works for the print case. Not quite sure this is the best way to do it, but it's better. 2013-06-18 17:47:13 -07:00

4d569f9112 In progress, temp commit. Have removed pubsub interface in favor of 0MQ sockets -- this gets us free message-passing across network or local host. 2013-05-29 14:18:15 -07:00

db34eca30e Refactored modes_rx to use a more modular radio interface (radio.py) using a pubsub pattern to formalize the old "outputs" interface I was using. Should make it easier to reuse the radio interface. 2013-05-27 19:50:42 -07:00

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

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.

4b70c5a0b0 Up the sample rate for RTL dongles to 3.2Msps. Seems to enjoy 3.2Msps just fine, and the Mode S RX works *much* better with the extra bandwidth. 2012-08-23 19:24:06 -07:00
