摘要: 这个程序用下拉菜单条的方式可变选取参数观测李萨如图形.用MATLAB编写-Abstract : This procedure using the drop-down menu, select the variable parameters observation Lissajous figures. using MATLAB

OFDM ―― OFDM(Orthogonal Frequency Division Multiplexing)即正交频分复用技术仿真。-OFDM- OFDM (Orthogonal Frequency Division Multiplexing) that is orthogonal frequency division multiplexing simulation.

SHA加密算法是目前广为应用的重要加密方法之一。而SHA-1 生成 160 位的消息摘要，虽然执行更慢，却被认为更安全。明文消息的最大长度可达到 264 位。下面是网络上流传的SHA算法，我们自己调试了一下，已经通过。现把主函数和算法函数贴出来。-SHA encryption algorithm is an important widely used encryption methods. And SHA-1 generates the message digest 160, although more slowly, but think more secure. Explicit messages the maximum length could reach 264. The following is a network spread SHA algorithm, debugging a bit of our own has passed. Are the main functions and algorithms function posted.

首先这个程序是在Linux下写的，然后在Windows的VC6中完善即调试通过，最后在Linux下调试运行，完全正确。-First of all, this procedure was written under Linux and then Windows in the VC6 debugger that is perfect through the final run in Linux under the debugger, entirely correct.
