data communication system and method for timing synchronization in data communication system

摘要

In the timing synchronization method in the data communication system of the present invention, a communication block receives a global synchronization signal including a global synchronization clock and a global synchronization pulse from a previous communication block, and transmits the received global synchronization signal to a next communication block. Performing global synchronization by the communication block and the next communication block using the global synchronization signal; Generating, by a master in the communication block, a local synchronization clock using the global synchronization clock; Generating, by the master, a local synchronization pulse using the local synchronization clock and the global synchronization pulse; Transmitting, by the master, the local synchronization clock and the local synchronization pulse to the slave; And performing, by the slave, local synchronization of synchronizing a start time of its own time slot to a start time of a time slot of the master using the local sync clock and the local sync pulse.
