数据辅助的载波相位跟踪，在第n个接收符号的DFT之后，导引子载波等于信道频率响应和已知符号的乘积根据余下的频率误差旋转以后的结果。(Data-aided carrier phase tracking in the first n months after receiving DFT symbols, guided subcarriers equivalent channel frequency response and known symbol of the product in accordance with rotation frequency error remaining after the results.)

关于matlab优化当中的一个多目标规划的一个源程序 很齐全很实用(The matlab optimization of a multi-objective planning of a source very complete and very useful)

function dg=gplus(x,y,z,x1,x2,y1,y2,z1,z2,p) G=6.67e-11 t222=myfun(x,y,z,x2,y2,z2) t122=myfun(x,y,z,x1,y2,z2) t212=myfun(x,y,z,x2,y1,z2) t221=myfun(x,y,z,x2,y2,z1) t211=myfun(x,y,z,x2,y1,z1) t121=myfun(x,y,z,x1,y2,z1) t112=myfun(x,y,z,x1,y1,z2) t111=myfun(x,y,z,x1,y1,z1) dg=-G*p*1e6*(t222-t122-t212-t221+t211+t121+t112-t111) 转化为g.u. function y=myfun(x,y,z,xi,eta,zeta) R=sqrt((xi-x).^2+(eta-y).^2+(zeta-z).^2) temp1=(xi-x).*log((eta-y)+R) temp2=(eta-y).*log((xi-x)+R) temp3=(zeta-z).*atan((zeta-z).*R/((xi-x).*(eta-y))) 书中所给公式 temp3=-(zeta-z).*atan((xi-x).*(eta-y)./(zeta-z)./R) 上式变换 y=temp1+temp2+temp3 (function dg = gplus (x, y, z, x1, x2, y1, y2, z1, z2, p) G = 6.67e-11 t222 = myfun (x, y, z, x2, y2, z2) t122 = myfun (x, y, z, x1, y2, z2) t212 = myfun (x, y, z, x2, y1, z2) t221 = myfun (x, y, z, x2, y2, z1) t211 = myfun (x, y, z, x2, y1, z1) t121 = myfun (x, y, z, x1, y2, z1) t112 = myfun (x, y, z, x1, y1, z2) t111 = myfun (x, y, z, x1, y1, z1) dg =-G* p* 1e6* (t222-t122-t212-t221+t211+t121+t112-t111) converted the Gu function y = myfun, (x y, z, xi, eta, zeta) R = sqrt ((xi-x). ^ 2+ (eta-y). ^ 2+ (zeta-z). ^ 2) temp1 = (xi-x).* log ((eta-y)+R) temp2 = (eta-y).* log ((xi-x)+R) temp3 = (zeta-z).* atan ((zeta-z).* R/( (xi-x).* (eta-y))) book given formula Temp3 =- (Zeta-z)* ATAN ((Xi-X)* (ETA-y)/(Zeta- Z)/R) the above formula transform Y = temp1+temp2+temp3 )

[FFT]_matlab中关于FFT的使用(理解频率分辨率、补零问题).( [FFT ] _ matlab on the FFT use (understanding the frequency resolution, zero problem ). )

说明：  运用主成分分析法和K均值聚类法来进行SAR影像变化检测(SAR image change detection using principal component analysis and K-means clustering)

分数阶傅立叶变换，chirp信号分解型实现分数阶傅立叶变换(Fractional Fourier transform, chirp signal decomposition-type realization of fractional Fourier transform)

该程序可以方便的求解出钢丝绳漏磁检测信号的自相关性(work out the self-relevent of wire rope signal)

matlab 例程，matlab辅助小波分析与应用一书的源代码，开发环境为matlab(Matlab routines, Matlab support wavelet analysis and the application of a source code development environment for Matlab)

基于内容的图像信息检索，主要采用小波纹理的方法进行检索。(Content-based image retrieval, mainly using Wavelet texture method to retrieve.)
