gr-dvbs2tx is a GNU Radio OOT module including transmitter blocks for software-defined radio and message passing simulation. This is a fork of drmpeg's gr-dvbs2 project. The receiver blocks are in gr-dvbs2rx.

The goal of this project is to build a software-defined DVB-S2 transmitter, based on the EN 302 307 V1.3.1 Second Generation framing structure, channel coding and modulation systems for Broadcasting, Interactive Services, New Gathering and other broadband satellite applications standard:

The baseband framing, baseband scrambling, LDPC (low density parity check), BCH (Bose, Chaudhuri, Hocquenghem), bit interleaver and physical layer framing and scrambling blocks are from G4GUO's DATV-Express Digital Amateur Television project datvexpress_gui (https://github.com/G4GUO/datvexpress_gui/tree/master/DVB-S2) and converted to GnuRadio 3.7.x.

Since the functionality of the CCM version of the DVB-S2 transmitter is already included in GNU Radio, this OOT implements a VCM/ACM (Variable/Adaptive Coding and Modulation) version of the DVB-S2 transmitter.

This implementation supports the following DVB-S2 System configurations:

System configurations not supported are:

1. Input Stream Synchronizer
2. Null Packet Detection
3. Wide-band mode
