Time Division Multiple Access(TDMA)network protocol uses the orthogonality of time to achieve channel sharing.Each node of the network works in term of time slot mode so collision and competition do not exist.TDMA network is a kind of synchronization network and must have unitive time benchmark and the time slot of node must synchronize with time benchmark.The technique of time slot is the key technique of the TDMA network protocol.%TDMA(时分多址)网络协议是利用时间的正交性实现信道共享,网内各个站点按照时隙方式工作,不存在发生碰撞和相互竞争问题。TDMA网络是一种同步网络,必须有统一的时间基准,站点的时隙必须与时间基准同步。因此,时隙同步技术是TDMA网络协议的关键技术。
