- 对于移动通信系统主要有两类衰落：大规模衰落和小规模衰落。大规模衰落表示由于大范围内移动而引起的平均信号能量的减少或路径损耗。而小规模衰落则表现为两种机制：信号的时延扩展和信道的时变特性。对于无线应用，信道的时变特性是由于发射机和接收机相对移动而造成传输路径的变化。这些传播条件的变化速率影响衰落率。如果存在大量反射路径而不存在视行信号分量，此时的小规模衰落称为瑞利衰落(Rayleigh fading)，接收信号的包络由瑞利概率分布函数统计描述。这种衰落也就是这次实验我准备研究的-system fo
学生信息管理系统1
- 学生信息的管理是学校经常遇到的问题。学生数量的积聚增加和学生认识制度的改革，在校学生的认识在不断增加，而学生管理人员则相对减少。加上我国大学基层学生管理工作的头绪多，内容杂，管理细，要求高，传统管理办法已基本不适应新形势的要求。如在校生的学籍、课程成绩、学费的缴纳与否、学生所在班级等，稍有不慎就会出现错误。同时学生成绩的手工登录与查询，是一项非常繁重而枯燥的劳动；学生缴费与否也不可出粗心大意，一个字的差别可能造成经济上的大损失；每年课程的变化都需要重新规划，耗费许多人才和物力，而且会因人的情绪烦
