说明：  matlab小波包去噪举例，对初学者很有用的一个短程序(matlab wavelet packet denoising for example, very useful for beginners a short program)

这个程序是用来对PLLpre进行仿真的，该思想基于多方面的考虑(This procedure is used to PLLpre simulation, based on the thinking of a number of considerations)

it is an M file code for butterfly effects.

Gaussian Distribution.

利用偏移量插值实现图像的透视变换（运用了双线性变换原理）(Offset interpolation using the image perspective transformation (using the bilinear transformation principle))

分析并实现了奇异谱斜率的方法，并把该方法用到了时域信号的检测。(Singular spectrum analysis and implementation of the slope method, and to the method used in the time-domain signal detection.)

2D-DCT 压缩图像后，通过QPSK,AWGN信道编码传输后，IDCT解压缩回原始图像，适用于任何图像(Using DCT to compress the orginal image, I use zigzag program, quantization, dct compression, then change the vector to bineary bit to pass through the QPSK channel. And from the binary array, I use IDCT to reconstructe the orignial image. working perfectly.)
