1. one kind in a peer-to-peer network in the first receiver device for performing the method for successive interference cancellation (SIC), described first receiver device is that described method comprises by the expection receiver of the first telephone traffic signal transmitted from the first transmitter apparatus:

  • Receive the first pilot signal from described first transmitter apparatus;

    Receive the second pilot signal from the second transmitter apparatus, described second transmitter apparatus of described second pilot signal instruction is intended to transmission second telephone traffic signal;

    Determine the first transmission rate from the traffic transmission of described first transmitter apparatus and the second transmission rate, wherein said first transmission rate be according to described first and the signal power of described second pilot signal and transmitting power than determining, and described second transmission rate is than determining according to the described signal power of described first pilot signal and described transmitting power;

    To described first transmitter apparatus transfer control message, described control message comprises described first and second transmission rates;

    The telephone traffic signal comprising described first telephone traffic signal is received from described first transmitter apparatus, described first telephone traffic signal comprises the first and second signal components, in described first signal component, overlapping described secondary signal component is to form described first telephone traffic signal, and described first and second signal components generate from the first and second code words respectively;

    From described described first code word receiving described first signal component of described first telephone traffic signal that telephone traffic signal decoding is transmitted by described first transmitter apparatus;

    If decoded described first code word success, then from described receive telephone traffic signal deduct through decoding the first signal component;

    Deducting described described second telephone traffic signal of remainder decoding by described second transmitter apparatus transmission receiving telephone traffic signal after the first signal component of decoding described in use;

    AndThe described second telephone traffic signal success if decoded, then deduct described the second telephone traffic signal through decoding from the described described remainder receiving telephone traffic signal, and from described second code word of remainder decoding by the described secondary signal component of described first telephone traffic signal of described first transmitter apparatus transmission receiving telephone traffic signal after deducting described the first signal component through decoding and described the second telephone traffic signal through decoding.
