KR970058153A - Traffic channel strobe signal generator of personal communication terminal - Google Patents

Abstract

In the present invention, when transmitting traffic data from a base station to a terminal in a half rate method, an individual can generate a strobe signal for a corresponding traffic channel based on a time slot number assigned through the base station and a reference clock of 13 MHz. The present invention relates to a traffic channel strobe signal generator of a communication terminal, wherein each data bit has a length of 48 clocks on the basis of a 13 MHz clock, and in the personal communication system configured to configure one time slot with 156.25 bits. A bit synchronous signal is generated based on the reference clock and the frame start signal, and then a time slot synchronous signal is generated based on the bit synchronous signal and the reference clock, and the time slot synchronous signal is counted to calculate a current time slot number. do. Subsequently, when the time slot number set from the outside is stored and the time slot number matches the counted time slot number, the time slot strobe signal is generated. When the counted time slot number reaches a predetermined value, the frame synchronization signal is generated, the frame number is calculated based on the frame synchronization signal, and the strobe signal of the traffic channel is generated based on the frame number. And an output means for outputting the strobe signal of the corresponding traffic channel in two frame periods from the strobe signal.
