摘要：
A local wireless signal receiving apparatus using digital RF processing technology including: a receiving digital RF processor receiving an RF signal and detecting an IF signal from the received RF signal; a zero-crossing signal detector detecting a zero-crossing signal from the detected IF signal, and converting the detected zero-crossing signal into a digital signal; and a receiving signal processor converting the digital signal into a local wireless signal.
