Abstract
본 발명은 단말기에서 기지국으로 독립제어채널(SDCCH)에 대한 제어데이터를 전송함에 있어서 기지국을 통해 할당받은 독립제어채널번호와 자체적으로 생성한 13MHz의 기준클록을 근거로 독립제어채널에 대한 시프트 클록신호를 생성할 수 있도록 된 개인통신용 단말기의 업링크시 독립제어채널 시프트 클록신호 발생장치에 관한 것으로, 이는 13MHz의 클록을 기준으로 하여 각 데이터 비트를 48클록의 길이로 함과 더불어, 156.25비트로 하나의 타임슬롯을 구성하도록 된 개인통신 시스템에 있어서, 13MHz의 기준클록과 프레임개시신호를 근거로 비트동기신호를 생성한 다음 이 비트동기신호를 근거로 타임슬롯동기신호와 148비트신호를 생성하게 된다. 이어, 이 타임슬롯동기신호를 계수하여 현재의 타임슬롯번호를 산정한 다음 이 타임슬롯번호를 근거로 0-타임슬롯 스트로브신호와 프레임동기신호를 생성하여 이 프레임동기신호를 계수하여 프레임번호를 산정하게 된다. 이어, 이 프레임번호데이터와 상기 148비트신호 및 기지국을 통해 할당된 독립제어채널번호를 근거로 독립제어채널에 대한 시프트 클록신호를 발생할 수 있게 된다.The present invention provides a shift clock signal for an independent control channel based on an independent control channel number assigned through the base station and a 13 MHz reference clock generated by the base station in transmitting control data for the independent control channel (SDCCH) from the terminal to the base station. The independent control channel shift clock signal generator in the uplink of a personal communication terminal capable of generating a signal, which is based on a clock of 13 MHz, each data bit is 48 clocks long, and one 156.25 bits In a personal communication system configured to configure a time slot, a bit synchronization signal is generated based on a 13 MHz reference clock and a frame start signal, and then a time slot synchronization signal and a 148 bit signal are generated based on the bit synchronization signal. Next, the current time slot number is calculated by counting the time slot synchronization signal, and then a 0-time slot strobe signal and a frame synchronization signal are generated based on the time slot number, and the frame synchronization signal is counted to calculate the frame number. Done. Subsequently, the shift clock signal for the independent control channel can be generated based on the frame number data, the 148-bit signal, and the independent control channel number assigned through the base station.
