Hi everyone,

I'm using Xilinx System Generator, and the situation is:

I'm transmitting a bunch of symbols from a constellation (say 256-QAM), and in the receiver the symbols are , of course, noisy.
To take a decision on the transmitted symbols, I've no better idea that comparing one by one with the original constellation symbols, and keeping the one closer (in euclidian distance sense) to the noisy one.

I'm ended using an Mcode block, but I'd like to hear some ideas of how can I do that efficiently

Thanks!
