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.
