The physical layer of WCDMA is explained in detail. The downlink physical channel structure, uplink physical channel structure and timing relationship between channels are described in detail.

用面向对象的方法实现置换索引(KWIC)，即根据输入的一句英文，依次将句首的第一个单词移位到句尾。(Object-oriented methods to achieve permutation index (KWIC), that is based on the input sentence in English, followed by the first word in the first sentence of the shift to the end of the sentence.)

编写一个控制台程序，模拟在ATM机的存款和取款过程，当输入给定的卡号和密码（初始卡号和密码到数据文件里查看）时，系统能登录ATM系统，根据用户的身份不同显示不同的程序界面；取款 　　每次取款金额只能为100的倍数，总额不超过2000元，不允许透支。且取款之后，要记录取款的金额和时间。 存款 　　每次存款金额只能为100的倍数，总额不超过2000元。 修改密码 　　新密码长度不小于6位，不允许出现6位完全相同的情况，只有旧密码正确，新密码符合要求，且两次输入相同的情况下才可以成功修改密码。(Write a console program to simulate the ATM deposits and withdrawals process, when you enter a given number and password (the initial number and password to the data file view), the system can log in ATM systems, according to the user' s identity different display different The program interface withdrawal amount each withdrawal can only be a multiple of 100, the total does not exceed 2,000 yuan, does not allow overdrafts. And withdrawals after the withdrawal of the amount to be recorded and time. Deposit Amount per Deposit only a multiple of 100, totaling no more than 2,000 yuan. Change Password New Password length not less than six, allowed six identical situation, only the old password is correct, the new password meets the requirements, and enter the same case twice before they can successfully change the password.)

对控制台窗口操作进行抖动，通过窗口句柄找到控制台窗口，通过快速移动窗口位置实现抖动效果(The operation of the console window is jittered, the console window is found by the window handle, and the jitter effect is achieved by moving the window position quickly.)

集合的运算：交、并、补（难度系数：1.1） 全集：大写字母 ‘A’~’Z’ 要求实现以下功能： 1、集合的输入：自动去掉重复和非法的字符 2、集合的显示：输出集合的全部元素 3、输出一个给定集合的补集 4、输出两个给定集合的交集和并集 (jiao bing bu)

基于Visual C++ 的win32控制台的程序，实现使用定时器的功能，(Visual C++ win32 console-based program, using the timer function,)

说明：  从专业设备上读取数据图像，并对其进行分析的代码。(from professional equipment to read data from images and analysis of its code.)

说明：  广义最小方差控制，较为完整，通过仿真亲测实用性较高，不需要实际数据，仅仅需要模型。(The generalized minimum variance control is more complete. It is more practical to test by simulation. It does not need the actual data, only needs the model.)

base64 decoder to decode the original char from base64 encoded string(base64 decoder)
