| 本文给出了一种可用于Beyond3G的帧结构,利用在物理帧中添加单载波调制的同步信道的方法来实现快速小区搜索。小区搜索过程主要包括时隙同步、帧同步和小区识别过程。本文通过对小区搜索算法的检测概率和虚警概率进行分析,推导出小区搜索的平均搜索时间来分析设计方案的性能。最后,通过在IMT-2000modelA信道环境下对小区搜索算法的性能进行仿真,验证了设计方案的正确性。 |

| Abstract: |
| This paper presents a frame structure in downlink for Beyond 3G mobile communication systems, which adds the single carrier modulated synchronization channel to realize fast cell search. The cell search process includes of algorithm slot synchronization,frame synchronization and Cell ID identification. The theoretical analysis of algorithm is composed of the probability of detection and the probability of the false alarm, which brings out the mean acquisition time. Finally, Simulation results are presented in IMT-2000 model A channel condition to evaluate the cell search algorithm. |
