SPIHT-algorithm
天在维普下载了一篇SPIHT算法改进的论文,(耿兴云,《基于改进SPIHT的静态图像编码》,电脑知识与技术:学术交流-2007年5期),我根据该文提出的改进算法,用Matlab来实现,却发现改进算法的程序运行速度比原算法还要慢,希望有兴趣的朋友进来看看,评论一下原因。(Days in the VIP downloaded a SPIHT algorithm to improve the paper, (Gengxing Yun, " based on improved SPIHT still image coding," Computer Knowledge and Technology: 5-year academic exchange-2 007), in accordance with this paper the improved algorithm Matlab to achieve, but found that the improved algorithm runs faster than the original algorithm is also slow, hope to have interested friends come to see, comment on why.)

现代信号处理 一个序列为 ,使用FFT分析其频谱:
1) 使用不同宽度的矩形窗截短该序列为M点长度,取M分别为: a) M=20 b) M=40 c)M=160 ;观察不同长度的窗对谱分析结果的影响;
2)使用汉宁窗、哈明窗重做1)
3)对三种窗的结果进行理论分析及比较。并绘出相应的幅频特性曲线
(Modern signal processing a sequence, using FFT analysis of the spectrum: 1) the width of the rectangular windows with different truncated point of the sequence length of M, take M, respectively: a) M = 20 b) M = 40 c) M = 160 observation windows of different lengths affect the results of spectral analysis 2) Hanning window, Hamming window redo 1) 3) the results of three windows and compare the theoretical analysis. And draw the corresponding amplitude-frequency characteristic curve)

faultysignal_with_noise
1. 构造含噪音的振动信号 faultysignal_with_noise,
2. 利用小波变换 Wavelet transform去噪,小波包 Wavelet packet transform 变换去噪,
3. 把两种去噪后的信号,分别用STFT ,FFT ,小波变换三种方法进行错误诊断(1. the vibration signal faultysignal_with_noise, which contains noise, is constructed.
2. using wavelet transform Wavelet transform denoising, wavelet packet Wavelet packet transform transform de-noising,
3. the two kinds of denoising signals are diagnosed by three methods, STFT, FFT and wavelet transform respectively.)
