说明：  bp是MATLAB应用中的预测算法，含有例题(BP and MATLAB)

信号、图像对其求傅里叶变换时很普遍的频域分析，本程序提供对一维信号进行傅里叶变换，提出单边、双边变换！(Signal, images of their demand is very common when the Fourier transform frequency domain analysis, the program provides one-dimensional signals, Fourier transform, the unilateral, bilateral transform!)

由matlab的commet函数改编而来，在原来基础上新增控制质点运动速度的功能(The commet by the matlab function adapted from the original particle motion based on the new speed control function)

基于随机集理论多目标跟踪算法matlab工具包，转自VoBN，真大牛大腿，还在犹豫什么。。(Based on the theory of random sets multi-target tracking algorithm matlab toolkit, carried VoBN, really big cow thigh!!)

说明：  这是旅行商问题的完全压缩包，很好用。算法的计算速度很快，而且收敛效果很好的。(This is the traveling salesman problem completely compressed package, very handy. Algorithm, and the calculation speed quickly effect is very good convergence. )

例4：在sinc(t)信号中叠加噪声，分析对应频谱 fs=100 采样频率,必须大于两倍基带信号最高频率 ts=1/fs 采样时间间隔 T=2 时间窗大小 ( x=x+0.1*randn(1,N) x=awgn(x,-10, measured ) figure plot(t,x) title( 时域信号图 ) xlabel( t /s ) y=fft(x,N) figure if mod(N,2)~=0 N=N-1 end f=linspace(0,fs/2,N/2) plot(f,abs(y(1:N/2))*2/N) title( 叠加噪声的sinc(t)信号频谱 ) xlabel( f /Hz ) figure y0=y(1:N/2) P=y0.*conj(y0)/N P=10*log10(P) plot(f,P) title( 功率谱 ) xlabel( f /Hz ) )

基于Matlab的图片中文字的识别与提取，仅供学习参考(Matlab based on the identification and extraction of the text in the picture, only to learn reference)

2008年出版的，最新的第四版的讲信号与系统建模和simulink的书籍，很是适合通信专业的参考！同时也可以作为matlab扫盲的书(Published in 2008, the latest talk about the fourth edition of Signals and Systems Modeling and simulink books, it is a reference for communication professionals! At the same time can also book as a literacy matlab)
