Time synchronization method and device based on combined synchronization of bit synchronization and frame synchronization

The invention relates to the technical field of wireless communication, in particular to a time synchronization method and device based on combined synchronization of bit synchronization and frame synchronization. According to the method, the position of a frame header correlation peak is detected by using a frame synchronization algorithm based on a difference correlation peak detection technology, and integral information near a correlation peak value is directly sent to a bit synchronization link to calculate an interpolation coefficient after bit synchronization, so that frame synchronization and bit synchronization are subjected to joint synchronization processing, and the frame synchronization and bit synchronization are combined to realize synchronous processing. And the operation complexity during time domain synchronization of the receiving end is greatly reduced. 本发明涉及无线通信技术领域，具体涉及一种基于位同步和帧同步联合同步的时间同步方法及装置。该方法利用基于差分相关峰检测技术的帧同步算法，检测到帧头相关峰的位置，并将相关峰值附近的积分信息直接送入位同步环节计算位同步后的插值系数，以此来将帧同步和位同步进行联合同步处理，大大减少了
