SIGNAL RECEIVING DEVICE FOR MEASURING CHARACTERISTICS OF WIRELESS COMMUNICATION CHANNEL AND MEASUREMENT METHOD OF CHARACTERISTICS OF WIRELESS COMMUNICATION CHANNEL

摘要

The present invention provides a receiving device for measuring characteristics of a wireless communication channel. The receiving apparatus according to an embodiment of the present invention reduces the strength of a signal having an image frequency among the results of the correlation operation performed based on the received signal and the pseudo-noise code signal to generate a band limit signal and converts the generated band limit signal. An analog signal processing unit for generating an intermediate frequency signal, an analog-to-digital conversion unit for converting the generated intermediate frequency signal into a digital signal, and a baseband signal and a baseband including DC components by demodulating the digital signal in phase and orthogonal phase. A digital signal processing unit for generating a demodulation signal formed of a signal having the same bandwidth as a band signal and repeating at regular frequency intervals, and generating an impulse response signal by reducing the strength of signals other than the baseband signal among the generated demodulation signals It may include.
