Description: 3、使用如下命令更改密码：
shell> mysqladmin -u root -p password ‘newpass’
Enter Password:*******
出现Enter Password的提示后输入原来的密码oldpass即可。
读者可以尝试其它所有本章介绍的方法。
4、首先以root用户的身份连接到服务器：
shell> mysql -u root -p
Enter password:*******
出现Enter password提后输入root用户的密码，然后即进入mysql客户机的交互模式，可以看到下面的提示：
Welcome to the MySQL monitor. Commands end with or \g.
Your MySQL connection id is 4 to server version: 3.23.25-beta-log
Type help or \h for help. Type \c to clear the buffer
mysql>
然后发布查询，直接键入题目中的语句：
mysql> SELECT User,Host FROM mysql.user
-3, use the following command to change the password: shell> mysqladmin-u root-p password newpass Enter Password :******* the Enter Password prompt appears enter the original password after you oldpass. Readers can try all other methods described in this chapter. 4, first of all to root the identity of the user to connect to the server: shell> mysql-u root-p Enter password :******* appear Enter password to enter the root after the user s password, and then entering the mysql client interactive mode , we can see the following prompt: Welcome to the MySQL monitor. Commands end with or g.Your MySQL connection id is 4 to server version: 3.23.25-beta-logType help or h for help. Type c to clear the buffermysql> and then release inquiries, directly type the subject of statement: mysql> SELECT User, Host FROM mysql.user

Description: 一、 本程序采用16QAM调制方式，对一串2进制信源进行调制，采用（7，4）循环码对信源做信道编码，用升余弦滚降函数进行基带调制，再调到高频信道；在信道上加入高斯白噪声，运用匹配滤波器解调，画出解调星座图，运用最小欧氏距离译码判决，再对信号进行信道解码，画出采用信道编码技术和不采用信道编码技术的误比特率图。-First, this program uses 16QAM modulation mode, for a string of two binary source is modulated, using (7,4) cyclic code of the source-channel coding to do with a raised cosine roll-off function for base-band modulation, and then transferred to a high frequency channel in the channel by adding Gaussian white noise, the use of matched filter demodulation, demodulation constellation plot, using the minimum Euclidean distance decoding decision, and then right channel signals, decoding, channel coding techniques used to draw and non- channel coding techniques using bit error rate plans.
