查询词典 guard band

In order to improve the uplink bandwidth utility, that is, keeping the guard band between conterminous ONU slots as short as possible, as well as avoiding the upstream data collision, OLT must take the RTT of ONU into account, when arranges the start and ending time of ONU's transmission window.

为了提高EPON上行带宽利用率（即尽量缩短相邻ONU时隙之间的保护带长度），同时避免上行数据冲突，OLT在安排给ONU的授权窗口的开始时间和结束时间时，必须要将ONU的距离考虑在内。

On the basis of comparison of several algorithms of the calculation of unstable resonator"s mode. Fast Fourier transform method is chosen in this paper. The model of multi-layer distribution of gain is established. Sampling granularity in real space used in FFT, quotient of guard band and distance between subsections are made certain respectively. The convergence criterion of root-mean-square of plural y which is the quotient of the optical field"s distributions separated by one pass is established. Under the circs of multi-kind of distribution of gain and different measurement of distortion, the output optical field distribution is calculated.

在比较了各种计算腔模方法的基础上，根据角谱传播理论，选择FFT算法，建立谐振腔内多层增益分布模型，分别确定了FFT算法的空间采样间隔、保护带系数和分段计算的距离，选取光场往返一次之比的均方根值收敛准则，计算多种增益分布、不同镜面变形时的谐振腔输出光场分布，同时计算该光场的远场分布和传输有限距离之后的分布。
