In order to achieve timing synchronization in cell search

this paper studies the Primary Synchronization Signals（PSS）and the Secondary Synchronization Signals（SSS）in Time Division Long Term Evolution（TD-LTE）systems and makes an analysis with the relevant simulation software.On the basis of the TD-LTE wireless integrated test system

it proposes a Digital Signal Processors（DSP）-based scheme that implements timing synchronization by using the characteristics of the synchronization signals

and introduces the implementation process

including timing synchronization

cell ID detection and cell ID number.This scheme has been applied to the development of TD-LTE radio frequency conformance test systems.
