Hi Marcus

Thank you for your quick response.

I think it works. I mean, i'm using an Error Rate block to compare the
Trellis Enoder's output and the Viterbi Combos' output (I'm also doing this
with the PCCC Encoder and the PCCC Decoder Combo blocks) and the results is
0 (like it should be).  But i'm not sure if i'm missing something because
the Viterbi Combo block (and the PCCC Decoder Combo) uses a constellation
parameter, doesnt that mean that it decodes and demodulates at the same
time? 
The OFDM Mod block makes a digital modulation, and the OFDM Demod block
demodulates it.
So, am I demodulating twice? I am new at this and i don't know if I am
wrong.

I'm sending you my flowgraph, if you could see it, i would be really
gratefull.

Thank you very much.

Pd: I though Rita's pcf was a user and I was answering a post. Sorry if I
was wrong. Like I said, I'm new at this.
