Abstract

본 발명은 휴대용 전화기 등의 개인통신장치에 대하여 단말기에서 기지국으로 제어데이터(Cｏｎｔｒｏｌ Dａｔａ)를 전송함에 있어서 기지국을 통해 할당받은 제어데이터번호와 자체적으로 생성한 13MHｚ의 기준클록을 근거로 4명의 가입자에 대하여 독립제어채널(SDCCH)에 대한 스트로브신호를 생성할 수 있도록 된 개인통신용 단말기의 다운링크 독립제어채널 스트로브신호 발생장치에 관한 것으로, 13MHｚ의 클록신호를 근거로 각 데이터비트에 대응하는 비트동기신호를 생성하고, 이 비트동기신호와 상기 클록신호를 이용하여 156.25비트의 구간을 갖춘 타임슬롯동기신호를 생성게 되고, 상기 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 생성한 후, 이 프레임번호와 4명의 가입자에 대하여 할당된 독립제어채널번호를 근거로 생성된 프레임번호를 비교하여 양 데이터 값이 일치하는 기간에 대응하는 타임슬롯 스트로브신호를 출력함으로써 4명의 가입자에 대한 데이터 송수신을 위한 독립제어채널 스트로브신호를 생성하게 된다.The present invention is directed to four subscribers based on a control data number assigned through a base station and a reference clock of 13 MHｚ which is generated by the base station in transmitting control data (C etc) to a base station for a personal communication device such as a mobile phone. The present invention relates to a downlink independent control channel strobe signal generator of a personal communication terminal capable of generating a strobe signal for an independent control channel (SDCCH), and a bit synchronous signal corresponding to each data bit based on a 13 MH 13 clock signal. Generate a time slot synchronizing signal having a period of 156.25 bits using the bit synchronizing signal and the clock signal, and perform data transmission / reception when the count value of the time slot synchronizing signal coincides with the reference time slot number. In addition to generating a timeslot strobe signal, the timeslot synchronization signal The frame synchronization signal is generated by using the time slot number generated according to the number, the frame synchronization signal is counted to generate a frame number, and then based on the frame number and independent control channel numbers assigned to four subscribers. By comparing the generated frame numbers and outputting the timeslot strobe signal corresponding to the period in which both data values coincide, the independent control channel strobe signal for data transmission and reception for four subscribers is generated.
