通过LS和DFT方法对OFDM实现了信道估计，并对估计后的信道同原始信道进行对比，还有不同信噪比下的误码仿真(Through LS and DFT method to achieve the OFDM channel estimation, and the estimated channel compared with the original channel, as well as the BER simulation under different signal to noise ratio )

如何在有限的缓存容量中尽可能的传输更多的信息是我解决的问题(How to transmit more information as much as possible in limited cache capacity?)

说明：  里面包含适用于Matlab 多元线性回归的代码(Code for Matlab Multiple Linear Regression)

i2c 测试demo，适用于i2c调试，可以适用示波器测量波形确认i2c是否通。(I2C test demo, suitable for I2C debugging, can be applied to oscilloscope measurement waveform to confirm whether I2C is passable.)

显示进度条的VB异步下载实例，在获取下载任务后，用ListView列表显示当前任务，使用了Subclass.ocx控件的下载程序示例，本实例虽是一个下载程序，但可学习到不少实用的知识技巧，比如网络下载的实现、ListView控件的使用、进度条的实现等。

this programme oper is very efficient

该代码可以模拟特定尺寸超音速斜切喷管模拟，若修改其中尺寸参数，可以达到模拟任何超音速流动。(The code can simulate the supersonic oblique-cut nozzle with a specific size. If the size parameters are modified, any supersonic flow can be simulated.)

切面图的fortran程序 大家随意-Section map we can look at the fortran program
