BANDPASS SAMPLING RECEIVER, AND METHOD FOR DESIGNING AND RECONSTRUCTING A FILTER THEREOF

摘要

Provided are a bandpass sampling receiver and a filter design and reconfiguration method thereof. The bandpass sampling receiver includes: an analog-digital converter converting an analog wireless signal into a digital baseband signal; and a complex baseband signal extraction unit generating a first path signal and a second path signal from the digital baseband signal and extracting a complex baseband signal using a relative sample delay difference between the first and second path signals, wherein the first path signal is a down sampled signal after the digital baseband signal is sample-delayed and the second path signal is a down sampled signal without sample-delaying the digital baseband signal.
