> How those tables were generated? Would it be possible to add them to libosm
Convolutional encoding tables were created by hand from the generator polynomials in the specification. They could be generated externally.

Some of the other tables (puncturing and interleaving) can be generated one way or another; others cannot and are directly taken from the specification.
