The algorithm is composed of downlink frame detection and sector PN code identification. Firstly, we can utilize both time-domain and frequency-domain frame detection algorithms to decide the timing offset, and achieve downlink synchronization.
首先,可分别采用时域帧起始检测算法和频域帧起始检测算法确定下行帧起始位置,完成下行同步;其次,提出分层搜索的扇区标识值识别算法,该算法能大大减少检测和识别时间。
