The two users usually include a near user (low path loss between the serving base station) and a far user (high path loss between the serving base station), and the base station allocates a lower first signal for the near user. The power is transmitted while a higher transmit power is allocated for the second signal for the far user. The far user directly demodulates the second signal (that is, the first signal is treated as noise), and the near user first demodulates the second signal (taking into account that the near-user farther user has lower path loss, the probability of successful decoding is high.

Each receiver 418 receives a radio frequency signal through its respective antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to a receive processor 470.
