If tick_rate is fractional rate_i variable is 0 and shouldn't be used in division. Change-Id: I660922683d837160e0546a0f339560d7d0965379
2019-07-18utils/fn_time: added clock_error to fn_time_deltaPiotr Krysik2-6/+9
Information about clock error is needed in order to transform frame number to hardware time - which is not ideal (i.e. different than BTS time). Change-Id: Icd77b88da0490d6c9565bf3df0342574b91aae6e
2019-07-18receiver/time_sample_ref: SDR hardware time trackingPiotr Krysik4-73/+137
Gr-gsm's receiver needs a stream of samples with sampling frequency that is integer multiply of gsm symbol rate. Many hardware receivers don't support such rates, and even if they do there might be error in their time source. Sample rate is adapted and corrected with use of a resampler. Moreover corrections are applied in the runtime so resampler's resample rate is changed dynamically. Those changes need to be tracked in order to be able to track time of the hardware after resampling. Hardware time tracking is needed to enable triggering of events in the hardware (i.e. frequency changes, burst transmissions). Changes were made in time_sample_ref and receiver in order to enable SDR hardware time tracking. Change-Id: Ide8149a5fc6c22700d3a4542115306a4dc682ff2

2019-07-18trx: renaming of old freq hopping block and creation of a new onePiotr Krysik13-37/+554
The old freq_hopper -controlling USRP frequency with use of tags - was renamed to freq_hopper_tag. The new one - freq_hopper_msg - that uses uhd_source or uhd_sink control message input was created. Change-Id: Ic867446314ef2ee6903cef85d48c280981132dae

2019-07-18Filter out SoapyAudio devicesVasil Velichkov7-8/+89
When gr-osmosdr is compiled with SoapySDR support and SoapyAudio is installed the audio device is picked as a first choice when detecting devices but grgsm tools are not able to work with audio devices. So in such cases the user has to always specify the correct SDR device in the args parameter which is a bit inconvenient. When args is not specified call osmosdr.device_find to get all devices and filter out unspported ones like SoapyAudio devices. When args is specifed just try to create osmosdr.source with whatever value has been specified. Add -l and --list-devices command line option that prints information about all detected devices. Example commands: grgsm_capture --list-devices grgsm_capture --list-devices --args=nofake grgsm_capture --args=uhd,type=b210 -a 111 capture.cfile grgsm_livemon --args=rtl grgsm_livemon --args=uhd,type=b210 Change-Id: Ib84081041ca6c2bc18b9da0c32bac9d3ecef65ca

2019-07-18Improve the TCH/H decoder logsVasil Velichkov1-1/+8
- Change "6,90 kbit/s" to "5.9 kbit/s" A typo reported in github ptrkrysik/gr-gsm#456 - Comment out the "Error! frame_nr:" message as it turns out to confuse users more then it actually helps debugging. - When voice-boundary detection is enabled write the name of decoded control channel messages Change-Id: I697ef944f30c4cabb62c888317dd3a7f8dcd5611

- The second argument of tch_h_decoder constructor is a string that accepts the value of MultiRate configuration element and not an enum like the tch_f_decoder decoder. - Make the demapper's burst sink required. - Make all parameters visible. - Rename the TCH/H Channel parameter to Sub-channel number. - Add the qa_tch_h_decoder test in the CMakeLists.txt - Fix several typos Change-Id: I92d4f49955c634df7d76f17cfb58d7106846c1bd
2019-07-18Major simplification and some argument changes in grgsm_capturePiotr Krysik1-167/+113
grmgs_capture tried to do too many things for a simple recorder. It was simplified by removing the receiver and ability to save data to bursts files. All other stuff that is not necessary for recording signal to disk was also removed: -setters/getters, -storing of parameters that never will be changed. The 'fc' parameter name was changed to 'freq' to follow GNU Radio guidelines. The 'shiftoff' parameter was removed. 'bb_gain' and 'if_gain' parameters were added. Variables specific to some of SDR's like: -gains at different stages, -bandwidth (not all devices can set it), -antennas (some devices have just one, some not), were moved to separate options group. What is left to be exposed is: -dc_offset_mode, -iq_balance_mode, -gain_mode. Change-Id: I092a43eaddb09a99c6cc05fde13f0ae94d9e0251
