超效率DEA

This a self-contained package including the 2-D DWT and inverse DWT routines. The included matlab routines are used to generate noisy example images and disply the result of denoising.

这是我自编的PQ分解法小程序，采用极坐标形式表示节点电压。(This is my small self of the PQ decomposition process is expressed by polar coordinates node voltage.)

在Matlab配件过滤器测​ ​ 振幅响应资料使用invfreqz。(Fitting Filters to Measured Amplitude Response Data Using invfreqz in Matlab )

频数统计，能够统计变量的出现的频数，还比较好用。(Frequency statistics, the statistical variables appear frequency, but also relatively easy to use.)

This code is to find out the PSNR between two different image, which shows the quality of both images

CC2530的定时器实验，使用IAR编写。(CC2530 key experiments, using IAR preparation procedures.)

DPSK系统的调制解调仿真，包括原理以及源代码和仿真结果，十分完整，包含了DPSK的相干解调，非相干解调，有自己的许多心得，希望对初学者有帮助(Modulation and demodulation of DPSK system simulation, including schematics and source code and simulation results, very complete, contains DPSK coherent demodulation, non-coherent demodulation many experiences, hope helpful for beginners)

用matlab来演奏张信哲的《过火》，比较有意思的一个程序(Matlab to play Jeff Chang' s " gone too far" , one of the more interesting program)

说明：  本算法是基于高斯分布的梯度边缘检测法，采用MATLAB实现(The algorithm is based on the Gaussian distribution of the gradient edge detection method, the use of MATLAB to achieve)
