Error correcting codes block

Hi All,

Does GNURadio the error correcting code (ecc) blocks ?
I have googled, and found some info
about directory gr-error-correcting-codes, but this folder is not in
GNURadio 3.3.
So, can any block in GNURadio3.3 do error correcting?

There is a Viterbi encoder/decoder block called ‘trellis’ and it handles
hard and soft decoding. What you need to do is find the generating
polynomial or convolutional code that matches your needs.
