Abstract

The present invention relates to a local wireless signal transmitting / receiving apparatus and method using digital radio frequency (RF) processing technology. When the local wireless signal transmitting / receiving apparatus has generated a local wireless signal to be transmitted, has diffused the frequency of the generated local wireless signal and thereby generats a baseband signal, it converts the generated baseband signal of the local wireless signal into phase information, converts the phase information into an RF signal by means of a polar modulator, and transmits the RF signal. Also, when the local wireless signal transmitting / receiving apparatus has received an external RF signal, it detects an intermediate frequency (IF) signal, detects a zero-crossing signal from the detected IF signal, then converts the detected zero-crossing signal into a digital signal, converts the converted digital signal into a local wireless signal which is a processable signal, and processes the local wireless signal. According to the present invention, AD / DA converters are replaced with a polar modulator and a ZXD, thus making it possible to implement a low-power design for a local wireless signaltransmitting / receiving apparatus, to reduce chip size and to save costs.

Description

technical field [0001] The present invention relates to local wireless signal transmission / reception technology using digital radio frequency (RF) processing, and more specifically, to the following local wireless signal transmission / reception device and method using digital RF processing technology, the device and method being applied to The transmission / reception system of local wireless communication converts the local wireless signal to be transmitted into an RF signal through digital RF processing, transmits the RF signal, detects an intermediate frequency (IF) signal from an external RF signal, and converts the detected IF signal The digital signal is then converted into a local wireless signal that can be processed. Background technique [0002] Wireless communication that can replace wired communication has been developed, and local wireless communication in wireless communication, such as Bluetooth, Zigbee, Ultra Wide Band (UWB: Ultra Wide Band), and Infrared Data A...
