    • A radio communication apparatus that transmits and receives a signal via an antenna duplexer, the apparatus that includes a dividing unit that divides part of a transmitting signal to be transmitted via the antenna duplexer. Also included is a conversion unit that converts a receiving signal of a first frequency band received via the antenna duplexer into a second frequency band lower than the first frequency band. In addition, the apparatus includes an extraction unit converting a noise component of the first frequency band included in the transmitting signal divided by the dividing unit into the second frequency band and extracting the noise component. Moreover, the apparatus includes an inversion unit that inverts the phase of the noise component extracted by the extraction unit. Also included is a combining unit that combines the receiving signal converted by the conversion unit and the noise component inverted by the inversion unit.
    • 一种经由天线双工器发送和接收信号的无线电通信装置,该装置包括划分单元,该划分单元将通过天线双工器发送的发送信号的一部分进行分割。 还包括将经由天线双工器接收的第一频带的接收信号转换成低于第一频带的第二频带的转换单元。 另外,该装置还包括一个提取单元,将由分割单元划分的发送信号中包括的第一频带的噪声分量转换成第二频带并提取噪声分量。 此外,该装置包括反转单元,其反转由提取单元提取的噪声分量的相位。 还包括组合单元,其组合由转换单元转换的接收信号和由反转单元反相的噪声分量。
