Abstract

본 발명은 휴대용 전화기 등의 개인통신장치에 있어서, 기지국으로부터 송신되어 온 프레임개시신호와 사용이 허용된 타임슬롯번호를 근거로 해당하는 타임슬롯(Time Slot)에 대한 다운링크 트래픽채널의 스트로부신호를 생성하도록 된 개인통신용 단말기의 할당된 타임슬롯에 대한 다운링크 트래픽채널 스트로브신호 발생장치에 관한 것으로서, 13MHz의 클록신호를 근거로 각 데이터비트에 대응하는 비트동기신호를 생성하여 이 비트동기 신호와 상기 클록신호를 이용하여 156.25비트의 구간을 갖춘 타임슬롯 동기신호를 생성하고, 상기 타임슬롯동기신호의 계수치와 자신에게 할당된 타임슬롯번호를 비교함으로써 데이터 송수신을 위한 다운링크 타임슬롯 스트로브신호를 생성하게 되며, 상기 타임슬롯 동기신호의 게수치를 근거로 현재의 타임슬롯번호를 산정한 후 그 산정된 타임슬롯번호를 이용하여 프레임동기신호를 생성하고, 이어 프레임동기신호를 계수하여 프레임번호를 생성하여 이 프레임번호와 할당된 프레임번호를 비교함으로써 데이터 송수신을 위한 트래픽채널 스트로브신호를 생성한 후, 상기 다운링크 타임슬롯 스트로브신호와의 논리곱을 통하여 할당된 타임슬롯에 대한 다운링크 트래픽채널 스트로브신호를 생성하게 된다.In the present invention, a personal communication device such as a portable telephone includes a straw signal of a downlink traffic channel for a corresponding time slot based on a frame start signal transmitted from a base station and a time slot number allowed to be used. A apparatus for generating a downlink traffic channel strobe signal for an allocated timeslot of a personal communication terminal, which generates a bit synchronization signal corresponding to each data bit based on a 13 MHz clock signal. Using the clock signal, a time slot synchronization signal having a period of 156.25 bits is generated, and a downlink time slot strobe signal for data transmission and reception is generated by comparing a count value of the time slot synchronization signal with a time slot number assigned thereto. The current time slot number is based on the number of timeslot synchronization signals. Calculates the frame synchronization signal using the calculated time slot number, and then counts the frame synchronization signal to generate the frame number, and compares the frame number with the assigned frame number. After generating the signal, a downlink traffic channel strobe signal is generated for the assigned timeslot through a logical product of the downlink timeslot strobe signal.
