Instrumental Variable Estimation Of A Threshold Model-matlab code

实现了PCM编码->基带码型转换（NRZ to HDB3）->QPSK调制->高斯信道->QPSK解调->基带码型反转换（HDB3 to NRZ）->PCM解码。同时给出了误码率曲线。(Achieve a PCM coding-> Baseband code converter (NRZ to HDB3)-> QPSK Modulation-> Gaussian channel-> QPSK demodulator-> anti-baseband conversion pattern (HDB3 to NRZ)-> PCM decoding. Also shows the BER curves.)

说明：  用matlab实现了FM调制解调过程，能很好地用图形来显示调制解调过程。(Achieved using matlab FM modulation and demodulation process, can well use the graphics to display modem process.)

基于matlab 的动态阈值 的白平衡算法，实现分区处理；(Dynamic threshold of the white balance algorithm based on matlab)

基于R-L模型的CT扫描和滤波反投影重建的程序实现(Based on CT scan and filter back projection reconstruction RL model program)

Windpower technology dates back many centuries. There are historical claims that wind machines which harness the power of the wind date back beyond the time of the ancient Egyptians. Hero of Alexandria used a simple windmill to power an organ whilst the Babylonian emperor, Hammurabi, used windmills for an ambitious irrigation project as early as the 17th century BC.
