| description | The invention provides a time-frequency self-synchronization method for a mobile ad hoc network. The method mainly solves the problems that the influence of measurement errors is large and clock drift is large during time synchronization. The method is based on a time-frequency self-synchronization algorithm of spread spectrum communication, realizes one-way distance measurement among mobile ad hoc network nodes through a signal processing means, can calculate clock difference parameters of each node relative to a source node in the mobile ad hoc network by combining with the accurate positions of the nodes, and compensates the clock difference and frequency difference by using the clock difference parameters of each node, so that the accuracy of distance measurement is improved. And time-frequency synchronization of each node and the source node is realized.
本发明提出一种移动自组网时频自同步方法，主要解决时间同步时测量误差影响较大且时钟漂移较大的问题。本发明是基于扩频通信的时频自同步算法，通过信号处理的手段，实现移动自组网节点间单向测距，结合节点的精确位置，可以计算出移动自组网网络中各节点相对于源节点的钟差参数，利用各节点的钟差参数补偿其钟差和频差，实现各 |
