PowerControlforWirelessData
- 随着蜂窝移动通信市场的巨大发展,下一代通信将是移动多媒体通信。这种情况产生了一个问题,如何对语音信源以外的多媒体信源进行功率控制。在探讨这个问题上,我们引入微观经济学中的数学模型和概念以及博弈论理论。在本文中,电话的通话质量被称为“效度”,对于一个CDMA电话通信的分布式功率控制被看作是一个‘非协作的博弈’。-CDMA mobile communication system is a technology which will be used in the next-generation com

- 求解过程中,由于几何模型发生变化而导致区域网格改变时会出现几何结构的连续性问题。本章中,我们举两个例子——流道中由于不同尺寸孔板引起额外压力损失问题是稳态几何连续性的一个例子。从概念来看,这个问题与第5章贝纳尔问题中通过Rayleigh数进行的变量连续性没什么不同。第二个例子是液体中悬浮的乳胶颗粒的干膜。在这个问题中,考虑了两个移动前缘;一个通过坐标变换,另一个通过光滑界面模型。该技术对于之前模拟该问题采用的移动弱项方法有所改进。-Solving process, due to geometry
Weighted-moving-average-method
- 加权移动平均法就是根据同一个移动段内不同时间的数据对预测值的影响程度,分别给予不同的权数,然后再进行平均移动以预测未来值。 加权移动平均法不像简单移动平均法那样,在计算平均值时对移动期内的数据同等看待,而是根据愈是近期数据对预测值影响愈大这一特点,不同地对待移动期内的各个数据。对近期数据给予较大的权数,对较远的数据给予较小的权数,这样来弥补简单移动平均法的不足。-Weighted moving average method is according to the degree of infl
Simple-moving-average-method
- 简单移动平均法是指对由移动期数的连续移动所形成的各组数据,使用算术平均法计算各组数据的移动平均值,并将其作为下一期预测值。 简单的移动平均的计算公式如下: Ft=(At-1+At-2+At-3+…+At-n)/n 式中,Ft--对下一期的预测值; n--移动平均的时期个数; At-1--前期实际值; At-2,At-3和At-n分别表示前两期、前三期直至前n期的实际值。-Simple moving average method refers to the da
