严格按照BP网络计算公式来设计的一个matlab程序,对BP网络进行了优化设计 优化1：设计了yyy，即在o(k)计算公式时，当网络进入平坦区时(<0.0001)学习率加大，出来后学习率又还原 优化2：v(i,j)=v(i,j)+deltv(i,j)+a*dv(i,j) (BP network in strict accordance with the formula to design a matlab program, the optimized BP network design optimization 1: Design of the yyy, that is, o (k) formula, when the network into the flat areas (< 0.0001) increase learning rate large, after the optimization of learning rate reduction 2: v (i, j) = v (i, j)+ deltv (i, j)+ a* dv (i, j) )

粒子群优化算法程序设计，非常有用的程序，希望对大家有用。。。。(Particle Swarm Optimization Program Design)

这个 压缩包含有完整的QPSK-MSK-QAM-OFDM调制解调m程序。希望对大家有帮助(This includes a complete compression QPSK-MSK-QAM-OFDM modulation and demodulation m program. We want to help)

这是我师兄做的空间谱估计的内容。这只是一小部分程序，希望大家能够接受，下载吧。(this done I saw the space Spectral Estimation content. This is only a small part of the procedure, hoping that everyone can accept, download it.)

说明：  利用matlab相关绘图功能制作图形文件(利用matlab相 ??绘???| 能制 ????形文 ?)

this help to draw delaunay triagles is input x,y to vectors represent coordinate of points for exemple p1(1,2) ,p2(3,4) p3(5,6) then x=[1,3,5] and y=[2,4,6]

信号与系统期末大作业。关于信号处理、零极点、时序频域分析。包含完整源程序源代码以及详细的实验报告。(Signals and systems ending job. Signal processing, poles and zeros, timing, frequency domain analysis. Contains the complete source code source code as well as a detailed lab report.)

用于产生线性调频信号，在时频分析中非常常用(used to proceed linear-time frequency modulated signal, it is very uesful in signal porcessing)
