Module dvbs2 

DVB-S2 CLI subcommand

This subcommand can be used to generate the LDPC codes used in the DVB-S2 standard. It will print the alist of the parity check matrix to stdout and optionally compute and print the girth of the Tanner graph. See crate::codes::dvbs2 for more information about the DVB-S2 LDPC codes.

Examples

The r=1/2, n=64800 parity check matrix for the normal FECFRAMEs can be generated with

$ ldpc-toolbox dvbs2 --rate 1/2

Its girth is computed with

$ ldpc-toolbox dvbs2 --rate 1/2 --girth
Code girth = 6

The n=16200 code for the short FECFRAMEs is generated with

$ ldpc-toolbox dvbs2 --rate 1/2 --short
