In IEEE 802.16m, these preambles are sent only once per superframe. 在IEEE802.16m系统中,前导码在每个超帧(SF)中只出现一次。
The hardware design adopts ultra-low power consumption MSP430 MCU as well as asynchronous MAC based on superframe structure. 在设计中采用了超低功耗的单片机并提出了超帧(SF)异步的通信方式。
Finally, a simple network is taken as an example, to make a more intuitive description of the implementation process and results of the routing algorithms, superframe scheduling algorithm, as well as the network management and maintenance scheme that are proposed in this paper. 最后,本文以一个简单的网络为例,直观的说明本文所提的路由算法、超帧(SF)调度算法、以及网络管理及维护方案等的执行过程和结果。
