这是本人做数据库课程设计时的仓促之作,自我感觉实际应用价值并不大,但可以给学VC和数据库编程的朋友做个范例。在做之前也参看了不少同类型的管理系统,收获不小,现将这个学生管理系统贴出来,希望能对有需要的朋友有所帮助。系统不足之处肯定不少,还请高手多多指教,欢迎跟本人联系。 本人在系统中添加了直接通过SQL语句对后台的表进行修改的功能,颇有争议,还请有实际开发经验的朋友指教。 本人正忙于考研,没时间写一个完整的程序说明,敬请谅解。如有问题,也可与本人联系。 QQ:332723187 EMAIL:wythust@163.com 当前系统用户和密码:(可改) 管理员级: administer 126 (Access加密密码也为126) 普通用户级: customer 123 teacher ttt 匿名用户级: anonymous (null)

Adaptive Filter. This script shows the BER performance of several types of equalizers in a static channel with a null in the passband. The script constructs and implements a linear equalizer object and a decision feedback equalizer (DFE) object. It also initializes and invokes a maximum likelihood sequence estimation (MLSE) equalizer. The MLSE equalizer is first invoked with perfect channel knowledge, then with a straightforward but imperfect channel estimation technique.

演示遍历二叉树的过程,所以首先建立二叉树,并用图形显示出树的形状。建立的过程是采用前序便利的方法来创建,设计两种生成树的方式:一种是系统随机生成,另一种是人工输入。考虑到屏幕界面的有限性,限定二叉树不超过5层,最多26个字符,输入字符小数点“.”代表NULL。初始树为某种颜色的结点,三种情况的遍历采用填充另外一种醒目的颜色,来表示当前遍历的结点,同时显示该结点的访问序号。同时在遍历的过程中在遍历图形的下方显示出遍历序列。
