Thank for catching the mistake. It is corrected now. Yes, the transmitter and receiver should agree on the set of codewords (the coding scheme) used. Receiver computes likelihood for all set of codewords and selects the one that maximizes the likelihood.

I wanted to tell you that I think there is a small mistake. One of your paragraphs begin with “In practice we don’t know Y (at the receiver) but we know x.” I think you mean ‘y’ (non capital) instead of ‘Y’. I think at the receiver we know Y, the set of all codewords. Later on, we can compute the hamming distances because we know this set. Isn’t this correct? Thanks for the explanation
