2019-05-02Improve 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
2019-02-05MacOS fixesVasil Velichkov1-0/+1
- Include grgsm/endian.h in tch_h_decoder_impl.cc - Revert 0ed39fbf9340bdfb254bec5e3b94d9f00cf9d151 as linking with boost_thread is needed Fixes GH-444 Change-Id: I00884962295082cff3eb64fa21e9f73437be0001

2018-12-29Add TCH/H decoder block with AMR multirate supportVasil Velichkov3-0/+418
Add new TCHH channel mode Add two new optional arguments -m CHAN_MODE, --mode=CHAN_MODE Channel mode. Valid options are 'BCCH' (Non-combined C0), 'BCCH_SDCCH4'(Combined C0), 'SDCCH8' (Stand-alone control channel) 'TCHF' (Traffic Channel, Full rate), 'TCHH' (Traffic Channel, Half rate) --sub-channel=TCH_H_CHANNEL TCH/H sub-channel. [default=0] --multi-rate=MULTI_RATE The MultiRrate configuration element from the Assigment Command message. Example: 28111a40. See 3GPP TS 44.018 - 10.5.2.21aa MultiRate configuration Example: grgsm_decode -m TCHH --sub-channel 0 --multi-rate 2811 -o voice.amr ...
