 Verdu's receiver consisted of a bank of matched filters followed by a Viterbi algorithm.In the context of the capacity of the narrowband Gaussian two-user multiple-access channel, Cover showed the achievability of the capacity region by means of a successive cancellation receiver, which decodes one user treating the other as noise, re-encodes its signal and subtracts it from the received signal.The same near-far resistance of the optimum receiver can be achieved with the decorrelating receiver proposed in.
