    • A quadrature modulator (202) takes out a part of a transmission signal and generates a cancel signal. A signal comparison means (300) compares the amplitude and phase of the cancel signal generated from the quadrature modulator (202) with those of a received signal and outputs a signal corresponding to comparison result to the quadrature modulator (202). The quadrature modulator (202) generates a cancel signal based on the output signal from the signal comparison means (300) and they perform feedback control such that the cancel signal and a leakage signal have an equal amplitude and become in-phase. A synthesizer (205) synthesizes the cancel signal outputted from the quadrature modulator (202) and its reverse phase cancel signal thus canceling the leakage signal.
    • 正交调制器(202)取出发送信号的一部分并产生取消信号。 信号比较装置(300)将从正交调制器(202)生成的消除信号的幅度和相位与接收信号的幅度和相位进行比较,并将与比较结果相对应的信号输出到正交调制器(202)。 正交调制器(202)基于来自信号比较装置(300)的输出信号产生消除信号,并且它们执行反馈控制,使得抵消信号和泄漏信号具有相等的幅度并变为同相。 合成器(205)合成从正交调制器(202)输出的取消信号及其反相消除信号,从而抵消泄漏信号。
