说明：  Hex文件转bin文件，源码，可根据需要扩展更多的应用。(Hex convert to bin,source code. Maybe extend to other application.)

说明：  The Radar Simulation GUI，雷达显示界面的代码，用matlab编写，包括所有的子程序，介绍文档。(I made this simulation as a project in a course I took in RADAR basic concepts. The RADAR is an Early Warning RADAR. The simulation simulates targets around the RADAR, calculates the expected return pulses and adds noise. The simulation works at the Intermediate Frequency (IF) level and I assume perfect phase reconstruction by the RADAR. )

刚学编程，多多指教(just learning programming, exhibitions)

说明：  QPSK调制信号通过高斯信道后输出BERvsSNR图像(QPSK modulated signal through Gaussian channel)

本代码能够正确实现H264的编码解码过程(This code can be correctly implemented H264 codec process)

1.写一个程序，它先接收一个字符串，然后显示其中数字符的个数、英文字母的个数和字符串的长度。 2.模拟密码输入：假设数据库中有密码5201314，用户输入一个字符串，显示的时候全都以*出现，然后判断用户输入的字符串是否与数据库中密码相同，若相同，输出“Password Right!”，否则输出 “Password Error!” 3.写一个程序，它先接收一个字符串，然后抽去其中的空格，最后按相反的顺序显示这个改变后的字符串。 4.找出负数的个数 5.求阶乘(1. Write a program that first receives a string and then displays the length in which the number of characters and English letters and the number of strings. 2. Analog password: 5201314 suppose password, the user enters a string of all time display to* appear, and then determine if the string entered by the user and the same password , if the same output Password Right! otherwise, output Password Error! 3. Write a program, it first receives a string, and then removing all spaces, and finally display the string in reverse order after this change. 4. Find the number of negative 5. factorial)
