SPREAD SPECTRUM MODULATION TECHNIQUES -spread spectrum - those modulation methods that are producing a signal whose spectrum is more wider than of the data signal, the occupied frequency band being independent by the signal of data band. -The sig

证据理论的基本原理的论文资料 证据理论采用信度的“半可加性”原则，较好地对不确定性推理问题中主、客观性之间的矛盾进行了折衷处理。而且，证据理论下先验概率的获得比主观Bayes方法要容易得多，已经成为构造具有更强的不确定性处理能力专家系统的一种有效手段。 -he basic principles of evidence theory papers information
