A gnuradio-companion flowgraph (dvbs2_tx.grc) for the bladeRF transmit capable SDR is included along with a stand-alone Python script for bladeRF (dvbs2-blade.py). A test Transport Stream that matches the example applications symbol rate, constellation and code rate can be downloaded here: http://www.w6rz.net/adv16apsk910.ts A DVB-S2 and DVB-S2X Transport Stream bit-rate calculator: https://github.com/drmpeg/dtv-utils/blob/master/dvbs2rate.c Note: This implementation supports the following DVB-S2 System configurations: 1) QPSK 1/4, 1/3, 2/5 2) QPSK 1/2, 3/5, 2/3, 3/4, 4/5, 5/6, 8/9, 9/10 3) 8PSK 3/5, 2/3, 3/4, 5/6, 8/9, 9/10 4) 16APSK 2/3, 3/4, 4/5, 5/6, 8/9, 9/10 5) 32APSK 3/4, 4/5, 5/6, 8/9, 9/10 6) CCM (Constant Coding and Modulation) 7) FECFRAME normal ***,800 bits 8) FECFRAME short 16,200 bits 9) Single Transport Stream 10) Roll-off 0.35, 0.25 and 0.20 System configurations not supported are: 1) VCM (Variable Coding and Modulation) 2) ACM (Adaptive Coding and Modulation) 3) Multiple Transport Streams 4) Single Generic Stream 5) Multiple Generic Streams 6) Input Stream Synchronizer 7) Null Packet Detection 8) Dummy Frame Insertion 9) Wide-band mode Note: DVB-S2X Broadcast services MODCOD's have been tested as of September 2016 with the Silicon Labs Si2183 demodulator. VL-SNR modes have been implemented, but are still untested. For DVB-S2X, optional Broadcast services configurations supported are ***APSK and ***APSK-L. 128APSK, 256APSK and 256APSK-L constellations are included for experimentation. https://www.dvb.org/resources/public/standards/a83-2_dvb-s2x_den302307-2.pdf Build instructions: mkdir build cd build cmake ../ make sudo make install sudo ldconfig Contributions are welcome!
