Hi @elSergio

I assume you are referring to the General TCM Decoder Block. The TCM Decoder Block employs soft Viterbi decision to decode the signal. You can verify is by using a Viterbi decoder block. In this block you can specify the decision type and decode the signal. You can leverage the following documentations to understand these topics better:

Thank you.
