APPARATUS FOR RECEIVING BAND PASS SAMPLING SIGNAL

摘要

PURPOSE: A BPS(Band Pass Sampling) signal receiving device is provided to down-convert a signal by constructing a signal processing algorithm without converting hardware. CONSTITUTION: An RF(Radio Frequency) filter(110) receives an RF signal of a band defined for receiving the RF signal. Two or more analog digital conversion units(120) generate a phase difference in order to enable the RF signal to include a time difference. Two or more interpolant filters(130) process digital signals of each RF signal including the phase difference. An adder(140) outputs the RF signals processed with interpolant filtering.
