Abstract: PURPOSE: A method for searching initial synchronization using a dummy code is provided to locate a dummy code delivery region within a frame for searching the initial synchronization, and to deliver a dummy code if traffic does not exist, to adjust the initial synchronization, thereby quickly searching the initial synchronization with simple hardware structure. CONSTITUTION: If a network synchronization transmission terminal enters a dummy code delivery region, the terminal checks a mode(405) and confirms whether a busy mode is set(406). If so, the terminal cancels delivery of a dummy code. If the busy mode is not set, the terminal checks a timer(407), and decides whether one of data regions is a dummy code region(408). If so, the terminal delivers the dummy code(409). If the region is not the dummy code region, the terminal rechecks the timer(407). The terminal checks the timer(410), and confirms whether the region is a synchronous region(411). If so, the terminal delivers a synchronous code(412).

Abstract: PURPOSE: A method for predicting the level of a receiving signal in an adaptive transmitting system is provided to predict the level of the receiving signal with a simple calculation by predicting the future value with the present value and the variation between the past value and the present value. CONSTITUTION: If a sample of signal to noise ratio for receiving is inputted(S22), a low pass filtering is performed to remove the rapid variation of the signal to noise ratio for receiving(S23). The level of the signal to noise ratio after a predetermined time is predicted by the variation of the filtered signal to noise ratio(S24). An average prediction error is calculated by the real value and the predicted value of the signal to noise ratio, and the predicted value is corrected by the average prediction error(S25). A prediction margin is added in the predicted value(S27).

Abstract: PURPOSE: A method and a device for processing satellite ATM(Asynchronous Transfer Mode) transceiving signals at 155-Mbps, are provided to enable the transceiving of 155-Mbps burst mode signals by using the satellite, and to define and implement a 155-Mbps transceiving format for the burst transceiving and afterward TDMA(Time Division Multiple Access). CONSTITUTION: A terrestrial network signal processing unit(100) performs terrestrial network signal processing for ATM(Asynchronous Transfer Mode) signals inputted from an ATM switch, for transmission to a satellite. A satellite signal receiving processing unit(200) processes ATM signals received from the satellite, and outputs the ATM signals to the ATM switch as terrestrial network signals. A transceiving control unit(300) is connected to the processing units(100,200) through buses, and controls the transceiving of ATM cells, then displays a control state. The number of zero(0) and one(1) dually received by bits in a predetermined byte of ATM cell counter, and a value over generality are decided as a received bit value. Residual bits are decided to extract an ATM cell counter value. The ATM cell counter is detected in a QPSK(Quadrature Phase-Shift Keying) demodulator(202), to transmit only IB(Internal Block) in a deframer(203) to an error correction decoder(204). ATM cells decoded in the error correction decoder(204) as much as the ATM cell counter value are delivered to a terrestrial network output ATM buffer(205). Viterbi decoding and interleaving functions are performed by IB blocks received from the error correction decoder(204), and RS(Reed-Solomon) decoding and descrambling functions are performed by the unit of RSB(RS Block). The descrambling-ended ATM cells are delivered to the terrestrial network output ATM buffer(205), and ATM cells accumulated in the buffer(205) are transmitted to a terrestrial network output signal processor(206). ATM cells received by being adjusted to a transceiving speed pre-configured in the terrestrial network signal processor(206) are transmitted to an ATM exchange through an optical fiber and a coaxial cable, with an STM(Synchronous Transfer Mode)-1 or a DS(Digital Signal)-3 protocol.
