SYNCHRONIZING METHOD IN DIGITAL RADIO SYSTEM AND SYNCHRONIZING CIRCUIT

摘要

PPROBLEM TO BE SOLVED: To reduce power consumption at a waiting time by using a synchronous system for minimizing an operating time. PSOLUTION: A synchronizing method in a digital ratio system has a master station and at least one slave station by a receiving means of the master station or the slave station. The method includes a step of measuring the error of the sample number of a receiver by a timing error detecting means and actually detected sample number always according to a period of an oscillating means, a step of subtracting a value of the measured error before one from the measured value by a subtracting means and outputting the value, a step of predicting a value changing during a pausing period by using a detecting period and a pausing period with an output as the error generated during the detecting period, a step of inputting an added value of the value changed by the prediction and the changed value before one to a frequency dividing counter, and a step of obtaining an accurate sample number immediately after the start of the receiving means.
