HEAD

• leandvbtx: Added real-time mode (-fill).
• leansdrserv: Network access to leansdr command pipelines.
• leaniio{rx,tx}: PlutoSDR support via libiio.
• leanmlmrx: Multi-channel FM demodulator.
• leandvb: Spectrum output, JSON syntax.
• leandvb, leandvbtx: DVB-S with non-standard constellations (with --viterbi).
• leandvb: Support all DVB-S code rates with --viterbi.
• leandvbtx: Support all DVB-S code rates.
• New viterbi_sync with simplified metrics (may degrade QPSK sensitivity).

2017-07-23 v1.2.0

• Fixed --hs mode on x86_64.
• Added --s8, --s16, --u16.
• Improved timing recovery at low SNR (small performance penalty).
• Added --hdlc mode (compatible with some satellite modems).
• Added benchmarking/test suite (test/leandvb_bench.sh)
• Added tools for benchmarking: leantsgen, leandvbtx, leanchansim.
• Added LOCKTIME output with --fd-info.
• Added --hs mode (high throughput for raw u8 QPSK 1/2).
• Added --drift.
• Filters follow --drift.
• Added --float-scale.
• Documented --fd-const.
• Renamed --probesize (was --maxsend).
• Added --viterbi.
• Added VBER (bit error rate after deconvolution, detected by RS).
• Added FFT-based CNR estimator.

2016-09-16 v1.1.0

• Support for DVB-S2 constellations (not FEC).
• Fixed --derotate.
• Fixed excess deconvolution errors with FEC7/8.
• Added simple baseband filter (not RRC).
• Added --fastlock mode for low SR and off-line processing.
• Added leandvb_vt100ui.sh with constellation plot.

2016-09-04 v1.0.0

• Development moved to git and github.
• leandvb is now distributed as part of leansdr.
• Support for all DVB-S code rates.
• Status output for third-party UIs: lock, MER, frequency offset.
• Software AGC is always enabled. rtl-sdr HW AGC is not recommended.
• stderr is quiet by default. Use -v -d for troubleshooting.
• Deconvolution is now algebraic (instead of look-up table).
• Added leansdrscan for cycling through DVB settings.
• Added leansdrcat for debugging real-time behaviour.

2016-02-29 Preview release of leandvb

• Code rate 1/2 only.
• Hard-decision deconvolution (without Viterbi).
