2018-12-29Add TCH/H decoder block with AMR multirate supportVasil Velichkov3-2/+64
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 ...

2018-08-10gsm_trx_burst_if: allow to customize the bind addressVadim Yanitskiy2-1/+3
Pleviously remote address for DATA interface was also used as the bind address, what is definitely wrong. Let's change the API a bit in order to allow one to specify a custom bind address. Change-Id: I6e5f7b7119ac454217b8dd04f9ee0dd3b23972b6

2017-11-05misc_utils/trx_burst_if: get rid of built-in timeslot filterVadim Yanitskiy1-4/+0
Since the API of 'Timeslot Filter' block was exposed, we can get rid of built-in timeslot filter and use the proper methods.
2017-11-05Refactor the 'TRX Burst Interface' blockVadim Yanitskiy3-9/+9
The following changes were made: - Both implementation and headers were merged with misc_utils - Fixed namespace mess: was gr::grgsm, became gr::gsm - More accurate class name was chosen: "trx_burst_if"

2017-07-22flow_control: implement pass / drop filtering policiesVadim Yanitskiy6-0/+60
This change introduces a set of three modes for flow control filters, one of which is default behavor and two extra modes else described below: - FILTER_POLICY_PASS_ALL - FILTER_POLICY_DROP_ALL Both modes are opposite, and make a filter either unconditionally pass or drop all the data one gets to the input. They would be usable for some external usage.

2017-07-19trx_interface: implement built-in timeslot filterVadim Yanitskiy1-0/+4
There is a dedicated block named 'Burst Timeslot Filter', which could be used, but one doesn't expose the API to change the timeslot index 'on fly'. This change implements built-in timeslot filter in 'TRX Interface' block, which will be used until the proper block expose API.
2017-07-07Implement transceiver interfaceVadim Yanitskiy3-0/+85
This change introduces a new block 'TRX Interface', which is aimed to provide an interface for external applications, such as Osmocom MS side stack implementation - OsmocomBB. Currently one allows to exchange raw GSM bursts between GR-GSM and other applications. Moreover, there is a new 'trx.py' application, which implements a simple follow graph, where all demodulated bursts are being sent to external application via UDP link provided by 'TRX Interface'. OsmoTRX (Osmocom's fork of OpenBTS transceiver) like control interface is used to initialize, configure, start and stop the application. Messages on this interface are human readable ASCII strings, which contain a command and some related parameters.
