    • PURPOSE: A wireless modem for cancelling noises and a method for cancelling noises using the same are provided to efficiently remove noises through a noise signal removal of a wireless modem when the noises of a device having a wireless modem is maintained in an antenna of the wireless modem. CONSTITUTION: A main antenna unit(110) receives a wireless signal including noise signal transferred from a device connected to a wireless modem, and a sub antenna unit(120) receives the noise signal. A noise signal adjustment unit(154) adjusts the noise signal of the sub antenna unit based on the correlation parameters between the noise signals of the main and sub antenna units. A noise signal remover(152) removes the adjusted noise signal from the wireless signal.
    • 目的:提供一种用于消除噪声的无线调制解调器和使用该无线调制解调器的噪声的方法,以便当具有无线调制解调器的设备的噪声保持在无线电的天线中时,通过无线调制解调器的噪声信号去除来有效地去除噪声 调制解调器。 构成:主天线单元(110)接收包括从连接到无线调制解调器的设备传送的噪声信号的无线信号,子天线单元(120)接收噪声信号。 噪声信号调整单元(154)基于主天线单元和副天线单元的噪声信号之间的相关参数来调整子天线单元的噪声信号。 噪声信号去除器(152)从无线信号中去除调整后的噪声信号。
