Abstract

The present invention relates to a kind of self-adaptive dual-binary turbo code encoding and decoding method based on DVB-RCS standard, relates to double-binary Turbo code coding in DVB-RCS standard satellite communication system return link RCST (Return Channel Satellite Terminal) small station Structure, interleaving algorithm, selection of puncturing pattern, Max‑Log‑MAP soft input and soft output decoding algorithm, CRC check, etc. The present invention calculates the CRC passing rate of the 100-frame data decoded by the receiving end in real time, generates a code rate adjustment factor, and feeds it back to the sending end to adjust the encoding code rate, so as to realize the optimization of the Turbo code rate and information transmission efficiency.

Description

technical field

[0001] The invention relates to a DVB-RCS standard-based self-adaptive dual-binary Turbo code encoding and decoding method, which belongs to the technical field of channel encoding. Background technique

[0002] VSAT (Very Small Aperture Terminal) refers to a satellite transmission system with an antenna diameter less than 2.4 meters and composed of a large number of earth stations. It can be directly installed at the user's place, so that the satellite communication can be directly oriented to the user or individual. Can provide high-quality voice, data, images and other integrated services. It is an important part of modern satellite communication and one of the important development directions of modern satellite communication.

[0003] DVB-RCS is ETSI (European Telecommunications Standards Institute, European Telecommunications Standards Institute), according to the characteristics of satellite communications, launched a set of industry standards that c...
