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.
In the context of wireless communication, Cover showed that the capacity region of a two-user multiple-access channel can be achieved through a successive cancellation receiver, which treats one user's signal as noise and re-encodes its signal before subtracting it from the received signal. This approach provides near-far resistance, similar to the optimum receiver, which can also be achieved with a decorrelating receiver.
