摘要
TD-SCDMA系统是时间同步系统,终端开机后首先要通过搜索下行导频时隙实现与NodeB的下行帧同步。文中首先分析了特征窗搜索算法的原理,然后详细阐述了在基于ZSP500的TD-SCDMA硬件平台下,具体的实现算法和详细设计方案。测试结果表明,该实现方案具有较理想的估计准确度和稳定性,这说明该方案适合应用于TD-SCDMA通信系统中。
TD-SCDMA is a time division synchronization system. Synchronization with Node B is achieved by searching the OwPTS UE. This paper first presents the principle of the DwPTS ＂unique window＂ searching algorithm, and describes the process and realization in detail on the hardware platform based on zsp500 in TD-SCDMA. The simulation results show that this algorithm performs well both in accuracy and stability in TD-SCDMA..
