Method for selecting a synchronous code in a mobile communication synchronic system

Abstract

The invention discloses a selecting method of a synchronization code for a mobile communication synchronization system. The method selects a binary code with zero correlation window as the synchronization codes for a mobile communication synchronization system, i.e. selects a binary code whose periodic autocorrelation and periodic cross-correlation have a zero correlation window, or whose aperiodic autocorrelation and aperiodic cross-correlation have a zero correlation window; and for former transmitting the synchronization codes uses cyclic and continuous mode and for later a protection time slot is added to said synchronization codes for transmitting. A width of said zero correlation window is defined according to that the width is greater than time delay spread of a multipath signal. Using the method, the selected synchronization code can implement more accurate synchronization.
