- A signal receiving device for measuring a characteristic of a wireless communication channel is provided. The signal receiving device includes an analog signal processor, an analog-digital converter, and a digital signal processor. The analog signal processor generates a band-limited signal by decreasing an intensity of a signal having an image frequency in a correlation operation result signal being a result of correlation operation, and generates an intermediate frequency signal by transforming the band-limited signal. The analog-digital converter converts the intermediate frequency signal into a digital signal. The digital signal processor generates a demodulated signal by performing in-phase/quadrature-phase modulation on the digital signal, the demodulated signal including a baseband signal, which includes a direct current component, and signals repeated at constant frequency intervals with a same bandwidth as the baseband signal, and generates an impulse response signal by decreasing intensities of the repeated signals in the demodulated signal.
