摘　　要：提出一种OFDM抗干扰技术的ZigBee网络时间同步算法,详细描述该算法的步骤,同时分析如何在ZigBee网络中实现该算法。研究了基于高速串行的数据调试算法,将它应用于并行的正交信道中去,提高了每个子信道的宽带时延,同时降低码间干扰对整个系统的影响,能够有效对抗多径效应,克服传统算法传输延迟的问题,最终通过测试平台上验证算法的可行性,使得该模型的时间同步算法能够在ZigBee网络节点上高效运行。Proposes ZigBee networks time synchronization algorithms based on non-leaky pulse-coupled oscillators model. The non-leaky pulse- coupled oscillators model has a linear dynamic, which solves the large computational complexity problem introduced by non-linear dynamic of classical pulse-coupled oscillators model. Therefore, the algorithm can be efficiently implemented on ZigBee nodes. Describes the details of the algorithm, analyzes how to implement the algorithm on ZigBee nodes, and introduces refractory period to eliminate the infinite firing loop problem. Finally, through the implementation on ZigBee nodes experiment, analyzes the factors of the synchronization and validates the feasibility of the algorithm.
