a mobile terminal is controlled via over - the - air feedback so as to enable its data transmissions to be independently and successfully decoded at each of the base stations in its active set absent a transmit power limitation or data retransmission limit . using the decoded data , the channel is re - estimated and the waveform received from the mobile terminal is reconstructed and subtracted from the total interference at each base station in the active set where decoding has been successful . as a result , transmissions from other mobile terminals , which have yet to be successfully decoded at such a base station , will experience a higher signal - to - noise ratio and thus an increased likelihood of being successfully decoded .
