SNR_MSE_analysis
小波变换（wavelet transform，WT）是一种新的变换分析方法，它继承和发展了短时傅立叶变换局部化的思想，同时又克服了窗口大小不随频率变化等缺点，能够提供一个随频率改变的“时间-频率”窗口，是进行信号时频分析和处理的理想工具。它的主要特点是通过变换能够充分突出问题某些方面的特征，能对时间（空间）频率的局部化分析，通过伸缩平移运算对信号（函数)逐步进行多尺度细化，最终达到高频处时间细分，低频处频率细分，能自动适应时频信号分析的要求，从而可聚焦到信号的任意细节，解决了Fourier变换的困难问题，成为继Fourier变换以来在科学方法上的重大突破。(wavelet transform)

PSO
This paper propose a Firefly algorithm (FA) for
optimal placement and sizing of distributed generation (DG) in
radial distribution system to minimize the total real power losses
and to improve the voltage profile. FA is a metaheuristic
algorithm which is inspired by the flashing behavior of fireflies.
The primary purpose of firefly’s flash is to act as a signal system
to attract other fireflies. Metaheuristic algorithms are widely
recognized as one of the most practical approaches for hard
optimization problems. The most attractive feature of a
metaheuristic is that its application requires no special
knowledge on the optimization problem. In this paper, IEEE 33-
bus distribution test system is used to show the effectiveness of
the FA. Comparison with Shuffled Frog Leaping Algorithm
(SFLA) is also given.

DCT
实现图像的DCT高通、低通滤波器并与傅里叶变换做比较.有图可见，经DCT低通滤波后，图像变得很模糊。因为DCT是FFT取其实部，能量减少，因此图像变得很模糊，没有经FFT滤波后的效果好。
经DCT高通滤波后的图像：
经DCT高通滤波后，图像的低频部分被滤除掉，图像变黑，只有边缘的痕迹可见。
(The DCT of image high-pass, low pass filter and compared with the Fourier transform.)
