Abstract

본 발명은 휴대용 전화기 등의 개인통신장치에 대하여 기지국에서 단말기로 제어데이터(Cｏｎｔｒｏｌ Dａｔａ)를 전송함에 있어서 기지국을 통해 할당받은 제어데이터의 프레임번호와 자체적으로 생성한 13MHｚ의 기준클록을 근거로 4명의 가입자에 대하여 다운링크 호출제어채널(PCH)에 대한 스트로브신호를 생성할 수 있도록 된 개인통신용 단말기의 다운링크 호출제어채널 스트로브신호 발생장치에 관한 것으로, 13MHｚ의 클록신호를 근거로 각 데이터비트에 대응하는 비트동기신호를 생성하고, 이 비트동기신호와 상기 클록신호를 이용하여 156.25비트의 구간을 갖춘 타임슬롯동기신호를 생성하여, 이 타임슬롯동기신호의 계수치와 기준 타임슬롯번호가 일치할 때에 데이터 송수신을 위한 타임슬롯 스트로브신호를 생성함과 더불어 상기 타임슬롯동기신호의 계수에 따라 생성되는 타임슬롯번호를 이용하여 프레임동기신호를 생성하고, 이어 이 프레임동기신호를 계수하여 프레임번호를 생성하게 되며, 이 프레임번호와 설정된 기준 데이터 값에 해당되는 프레임번호를 비교하여 양 데이터 값이 일치하는 기간에 출력되는 신호를 근거로 해당 호출제어채널의 프레임번호에 대응하는 타임슬롯 스트로브신호를 출력함으로써 데이터 송수신을 위한 호출제어채널 스트로브신호를 생성하게 된다.According to the present invention, in the transmission of control data (C ANT ANT R ANT ATA) from a base station to a terminal for a personal communication device such as a mobile phone, the present invention is based on a frame number of control data allocated through the base station and a reference clock of 13 MHｚ which is generated by itself. The present invention relates to a downlink call control channel strobe signal generator of a personal communication terminal capable of generating a strobe signal for a downlink call control channel (PCH) to a subscriber, and corresponding to each data bit based on a 13 MHｚ clock signal. A bit synchronization signal is generated, and a time slot synchronization signal having a period of 156.25 bits is generated using the bit synchronization signal and the clock signal, and data is generated when the count value of the time slot synchronization signal and the reference time slot number coincide. In addition to generating a time slot strobe signal for transmission and reception, The frame synchronization signal is generated by using the time slot number generated according to the coefficient of the signal, and then the frame synchronization signal is counted to generate the frame number. The frame number corresponding to the set reference data value is compared. Therefore, the call control channel strobe signal for data transmission and reception is generated by outputting the time slot strobe signal corresponding to the frame number of the call control channel based on the signal output in the period in which both data values coincide.
