2020-03-16: Matthias P. Braendli <[email protected]>
(v2.4.0):
Put more code in common with the other ODR-mmbTools.
Rework EDI input, which is now always compiled-in and preferred
to ZMQ input (for standards compliance).
Add native Lime support.
2019-07-08: Matthias P. Braendli <[email protected]>
(v2.3.1):
Add analog bandwidth setting for UHD and SoapySDR outputs.
Implement 10s check for ZMQ input, resetting the socket if no
data arrives.
Fix compilation against UHD 3.14.
Add EDI-over-TCP input.
Other minor fixes for GUI and ODR-DabMod.
2019-01-23: Matthias P. Braendli <[email protected]>
(v2.3.0):
Many improvements on GUI and DPDCE: It is now possible
to control the predistortion entirely through the web GUI.
See `python/README.md` for more.
Add SDR temperature to RC and munin.
Fix I/Q s16 output format.
SoapySDR output: do not set master clock rate if it is 0.
Fix warning about feedback server.
Fix digital gain being forgotten after an input stream interruption.

2018-08-07: Matthias P. Braendli <[email protected]>
(v2.2.0):
Fix bug in CFR implementation that was introduced in v2.1.0.
Make the ZeroMQ list command return JSON.
Add a few GPSDO stats to munin.
Make sure changes applied through RC stay after an internal modulator reset.
Remove the boost dependency.
2018-05-29: Matthias P. Braendli <[email protected]>
(v2.1.0):
Add s16 output format.
Add compilation target for the EasyDABv3, which
doesn't have boost and requires constellation points
output. This required changing the configuration file parser.
Avoid RC crash when setting invalid values.
2018-03-21: Matthias P. Braendli <[email protected]>
(v2.0.0):
Big rework of the SDR device handling, putting in common more
logic between UHD and SoapySDR. Goal is to enable SoapySDR devices
to be used for SFN and for DPD. (Not yet possible)
Replace the old timestamp path that went around the process flowgraph
by a new metadata path that goes through the flowgraph, to avoid the
issues with misalignment of frame and timestamps. Do not mix different
versions when using timestamps, and be careful when mixing ODR-DabMod
with other transmitters in SFNs, as the timestamp interpretation can
change!
Fix TII carrier selection.
Add OFDM symbol windowing for improved shoulder performance.
Add a timeout to the ZeroMQ input to quit on SIGINT (Ctrl-C).
Optionally show the flowgraph metadata in the file output for
test purposes.
Add antenna selection to UHD and SoapySDR outputs.
Make EDI input optional (it's not well tested, unfinished and slows
compile time)
Improve portability for non-Linux POSIX systems.
Default to TM 1, do not read from ETI anymore.
Add support for UHD 3.11.
Implement auto-reconnect for the TCP input.
2017-11-18: Matthias P. Braendli <[email protected]>

Fix TII insertion power level.
Fix bug in parsing timestamps appearing in rare conditions.
Add Crest Factor Reduction prototype.
Cleanup console output of flowgraph statistics.
Add prototype for Digital Predistortion.
Enable some additional compiler warnings.
Add some useful UHD statistics to RC.
Add configure option to disable march=native.
2017-06-05: Matthias P. Braendli <[email protected]>

of multiprocessor systems.
Give explicit names to GainControl modes (fix, max, var) in
configuration.
Add u8 IQ output format.
Add a normalised complexf IQ output format.
Make resampler unity-gain, i.e. remove digital_gain - sample rate
dependency.
Read UHD async messages in separate thread to lessen influence on the
time-critical transmit thread.
Pre-fill UHD IQ buffer before starting to stream data, to ensure it is
properly filled and reduce underruns.
2017-03-03: Matthias P. Braendli <[email protected]>

* odr-dabmod:
Add ETI-over-TCP input.

2012-08-01: Matthias P. Braendli <[email protected]>
(tag r1):
* crc-dabmod/*:
It is now possible to run dabmod with OutputUHD even
when no external 10MHz reference nor 1PPS are used.
When using FIRFilter, the TimestampDecoder keeps one delay value
to compensate for the increased pipeline latency of the FIRFilter.
As a consequence, it should be possible to synchronise two DABMODs,
even if only one uses FIRFilter.
