    Thanks for the info. The course is definitely useful. However, I think my question is more specific. If anyone can answer my question, please let me know. Thx.

    I have used this core. The TCM is simply a shift register with taps going through an XOR (modulo 2). What the taps are depends on the code used in the Viterbi Decoder.
