RECEPTION DEVICE FOR MEASURING CHARACTERISTICS OF WIRELESS COMMUNICATIONS CHANNEL, AND METHOD FOR MEASURING CHARACTERISTICS OF WIRELESS COMMUNICATIONS CHANNEL

摘要

Provided is a reception device for measuring characteristics of a wireless communications channel. According to an embodiment of the present invention, the reception device comprises: an analog signal processing unit for generating a bandwidth-limited signal by reducing the intensity of a signal having an image frequency among results of a correlation operation which is performed based on a received signal and a pseudo noise code signal, and converting the generated bandwidth-limited signal to generate an intermediate frequency signal; an analog-to-digital conversion unit for converting the generated intermediate frequency signal into a digital signal; and a digital signal processing unit for in-phase and quadrature-phase-demodulating the digital signal, generating a demodulation signal formed with a baseband signal including a DC component, and a signal which has the same bandwidth with the baseband signal, and is repeated at regular frequency intervals, and reducing the intensity of a remaining signal except for the baseband signal among the generated demodulation signals to generate an impulse response signal.;COPYRIGHT KIPO 2016
