Abstract

본 발명은 무선전화기의 채널자동변환장치 및 그 방법에 관한 것으로서, 채널을 고정하는 위상동기루프와, 잡음을 검출하는 잡음검출부와, 상기 잡음검출부의 신호에 의해 제어신호를 출력는 제어부와, 상기 휴대장치와 고정장치간 무선 송수신을 중계하는 무선중계부와, 채널을 검색하는 과정과 재설된 채널의 상태를 통보하는 표시부를 구비한다. 따라서, 본 발명은 별도의 채널변경부를 구비하지 않고 알고리즘의 변경과 하드웨어적인 기능을 간단하게 설정함으로써 자동으로 최적의 채널을 변경하여 고품질의 통화품질을 획들할 수 있다.The present invention relates to a channel automatic conversion apparatus and method for a wireless telephone, comprising: a phase synchronization loop for fixing a channel, a noise detector for detecting noise, a controller for outputting a control signal based on a signal of the noise detector, and the portable device. A wireless relay unit for relaying radio transmission and reception between the device and the fixed device, and a display unit for notifying the process of searching for channels and the status of the reset channel. Therefore, the present invention can automatically change the optimal channel by simply changing the algorithm and the hardware function without providing a separate channel changing unit, thereby capturing high quality call quality.
