Abstract
1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION
시분할방식을 이용한 디지탈 셀룰라 방식.Digital cellular method using time division method.
2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention
구조가 단순하며, 주파수 보정버스트를 빨리 찾아내는 GSM단말기에서 주파수 보정버스트 검출장치를 제공한다.The structure is simple and provides a frequency correction burst detection device in a GSM terminal that quickly finds the frequency correction burst.
3. 발명의 해결 방법의 요지3. Summary of the Solution of the Invention
시분할방식을 이용한 디지탈 셀룰라 방식에서 기지국에 동기되는 신호를 찾아내는 장치는 수신되는 고주파신호를 복조하여 인페이스신호를 출력하는 GSM RF수신부와, 미리 설정된 설정주파수 검출부를 구비하며, 상기 설정주파수 검출부에 의해 상기 설정주파수가 입력될시 일정레벨의 데이타를 출력노드단자로 출력하는 톤디코더부와, 상기 톤디코더와 병렬위치하며, 상기 톤디토더부의 출력이 없을시 일정레벨의 전원전압을 상기 출력노드단자로 인가하는 단자와, 상기 출력노드단자의 전압을 반전하는 반전부와, 상기 반전부의 출력을 입력하여, 처리하는 제어프로세서로 구성한다.In a digital cellular method using a time division method, a device for finding a signal synchronized with a base station includes a GSM RF receiver for demodulating a received high frequency signal and outputting an in-face signal, and a preset frequency detector. When the set frequency is input, the tone decoder unit for outputting a predetermined level of data to the output node terminal, and in parallel with the tone decoder, when there is no output of the tone decoder unit, the power supply voltage of a predetermined level is the output node terminal And a control processor which inputs and processes a terminal to be applied to the terminal, an inverting unit for inverting the voltage of the output node terminal, and an output of the inverting unit.
4. 발명의 중요한 용도4. Important uses of the invention
톤디코더를 이용하여 더 간단한 구성 및 더 빠른 시간에 주파수 보정버스트를 찾아낸다.The tone decoder is used to find frequency correction bursts in a simpler configuration and faster.
