Dimitri Stolnikov 582acdf444 add frequency and gain controls to rtlsdr receiver 2012-06-07 14:29:26 +02:00
Dimitri Stolnikov 2037ebeac6 add rtlsdr based receiver with click & tune functionality 
Call it with

 src$ ./demod/python/rtlsdr-tetra_demod_fft.py -s 1.8e6 -f 394.6e6 -g -1 -o /dev/stdout | ./float_to_bits /dev/stdin /dev/stdout | ./tetra-rx /dev/stdin

- Adjust the center frequency (-f) and gain (-g) according to your needs.
- Use left click in Full Spectrum window to roughly select a TETRA carrier.
- Use left click to fine tune the carrier by clicking on the left or right side of the spectrum.

Sylvain Munaut 1bc5434a99 lower_mac/viterbi: Use the high level API of conv.h from libosmocore 
It's more stable ... here we just need a flexible length, which we
can 'fake' by creating a local copy of the 'code' definition on the
stack.

Harald Welte 2840dc5f07 don't decode NULL pdu or TL-SDU of non-starting LLC segments 2011-04-24 11:45:20 +02:00
Harald Welte b5d6edbb82 Introduce LLC layer that has been completely missign so far 
All our MM/CMCE/SNDCP 'decodes' were broken previously, as they
assumed that the MM/CMCE/SNDCP message follows immediately after the
MAC header.  However, there's the LLC layer in between.

This is just simple LLC decoding and does not do re-assembly yet.
