ptrkrysik 821c87ca09 Added some info about python blocks. 2014-12-13 11:41:10 +01:00
ptrkrysik 2e5b7fb1c6 Corrected sch_detector 'np.complex64' occurences to 'complex64'. 2014-12-13 10:11:51 +01:00
ptrkrysik 3be74a732b Changed grgsm install directories and prefixes from "gsm" to "grgsm". The old prefix caused conflicts with libraries already available. 2014-12-13 10:11:00 +01:00
Piotr Krysik 6985131999 Update
Commented import that caused problems with running/pybombs installation.

Piotr Krysik d6cc0690c3 Update 2014-12-06 20:56:19 +01:00
ptrkrysik 529895b14c Updated copyleft statements of my files #3 2014-12-02 18:07:38 +01:00
ptrkrysik 4c538bae54 Removed unused samp_rate parameter from clock_offset_control 2014-11-28 23:40:12 +01:00
ptrkrysik 381253a1d2 Changes in clock offset corrector and gsm_input - the previous version wasn't working well when samp_rate_in was different from samp_rate_out.
Now resampling is done outside of clock offset corrector.

ptrkrysik e518bbfedd Added capability to receive multiple channels of a single BTS to the receiver. It is now possible to receive bursts on channels for which frequency hopping was used. Changed examples to work without hierarhical GSM Receiver block. 2014-11-06 14:50:59 +01:00
ptrkrysik dac3b2a309 Added new block which adapts stream of samples to GSM receiver's input requirements (integer multiply of 1625000/6 symbol rate, LP filtering) 2014-11-06 14:47:33 +01:00
ptrkrysik b108d6b7c7 Removed receiver_hier and wireshark_sink 2014-11-06 13:51:02 +01:00
ptrkrysik 62215e8ce0 changed name of a variable to better reflect it role in clock_offset_control 2014-10-30 08:59:38 +01:00
Piotr K 66bb3cdc31 Changed directory structure.
Corrected clock_offset_corrector (for some streange and yet unknown reason fractional resampler eats strem tags for some values of sps).

Piotr K 77f3b06949 Changed name of conditional_reset() to timed_reset(). Added line to stop timer if synchronization was achieved by the receiver. 2014-08-07 23:04:43 +02:00

piotr d8506d68db Changes to sch detector - it is not fully working yet 2014-07-20 23:52:57 +02:00

piotr 299ff0ea5e Added missing 2014-07-20 23:49:48 +02:00
piotr 6b78abc7bd Added new blocks written in python for new experimental gsm receiver.
FCCH burst tagger is element of hierarchical block - FCCH detector that adds tags after every detected FCCH burst. The value of each tag is a frequency offset estimate.
SCH detector waits for tags from FCCH detector which are used to find SCH burst position. It is unfinished.
