    • A communication device according to an embodiment of the present invention includes a communication antenna that receives a transmission signal where a spectrum spread signal subjected to a spectrum spread is modulated; an intermediate frequency converting unit that converts the transmission signal received by the communication antenna into an intermediate frequency signal having a predetermined frequency; an analog to digital converting unit that discretizes the intermediate frequency signal and outputs a discretization signal; a noise removing unit that detects a noise other than a normal thermal noise included in the discretization signal and removes the detected noise from the discretization signal; and a demodulating unit that demodulates the spectrum spread signal, based on the discretization signal that is output from the noise removing unit.
    • 根据本发明实施例的通信设备包括:通信天线,其接收经过频谱扩展的频谱扩展信号被调制的发送信号; 中频变换单元,其将由通信天线接收的发送信号转换为具有预定频率的中频信号; 模数转换单元,其离散中频信号并输出​​离散化信号; 噪声去除单元,其检测离散化信号中包括的正常热噪声以外的噪声,并从所述离散化信号中去除检测到的噪声; 以及解调单元,其基于从噪声去除单元输出的离散化信号来解调频谱扩展信号。
