摘　　要：目前我国自主研发的第三代移动通信标准TD-SCDMA已经成功商用。基于TD-SCDMA的物理帧结构特性,该文设计了一种用于下行同步码组捕获与精确帧同步的单信号点峰均比判决算法。MATLAB仿真结果表明:新算法在复杂度低于传统算法的同时,具有较高下行链路帧同步准确性。Currently, TD-SCDMA, the third generation mobile communication standard which China has independently developed, has been applied widely. Based on the physical frame structure of TD-SCDMA, we propose an algorithms of single code sequences peak average ratio correlation decision, used in TD-SCDMA downlink synchronization detection and frame synchronization precision, then we verify algorithm by MATLAB, and the result shows a high synchronization accuracy at lower complexity compared with the conventional method.
