计算循环平稳信号的4累积量的快速算法，希望对大家有所帮助(Cyclostationary signals calculated cumulant 4 fast algorithm, and they hope to help everyone)

ga 算法 量子优化计算方法 详细代码(ga Algeria liaangzi good method )

此程序对BPSK调制、载波锁频跟踪进行仿真，主要目的是锁频环 (sintable(k+1)=sin(2*pi*k/2^10) costable(k+1)=cos(2*pi*k/2^10) )

实现傅里叶变换高通、低通滤波，理想滤波，各种滤波因子。(Fourier transform to achieve high-pass, low-pass filtering, ideal filtering, filter factor.)

Fast mex K-means clustering algorithm with possibility of K-mean++ initialization (mex-interface modified from the original yael package https://gforge.inria.fr/projects/yael) - Accept single/double precision input - Support of BLAS/OpenMP for multi-core computation Please run mexme_yael_kmeans.m to compile mex-files (be sure that mex -setup have been done at least one) Run demo "test_yael_kmeans.m"(Fast mex K-means clustering algorithm with possibility of K-mean++ initialization (mex-interface modified from the original yael package https://gforge.inria.fr/projects/yael) - Accept single/double precision input - Support of BLAS/OpenMP for multi-core computation Please run mexme_yael_kmeans.m to compile mex-files (be sure that mex-setup have been done at least one) Run demo "test_yael_kmeans.m")

完成DSSS调制解调功能 mode[1，2] 1进行调制，2进行解调，未指定时自动完成这两个功能(Completion of DSSS modulation and demodulation functionality mode [1,2] 1 modulation, 2 to carry out demodulation, when the auto-complete does not specify that these two functions)

第一个是CDMA伪随机序列的自相关。第二个是CDMA系统。(The first is the pseudo-random sequence CDMA autocorrelation. The second is the CDMA system.)

说明：  Taylor算法，可以用于解非线性方程组(Taylor algorithm, can be used for solving the nonlinear equations)

设计一个低通数字滤波器，满足如下设计指标： 通带截止频率：0.2pi，通带波动：1dB 阻带截止频率：0.3pi，阻带衰减：15dB 要求：采用切比雪夫Ⅱ型滤波器原型，并分别采用脉冲响应不变变换法和双线性变换法进行设计，比较设计的结果，并进行分析 (Design a low pass digital filters that meet the following design specifications: passband cutoff frequency: 0.2pi, pass-band fluctuations: 1dB stopband cutoff frequency: 0.3pi, stop-band attenuation: 15dB requirements: use of Chebyshev filter prototypes with type Ⅱ and pulse response were the same transformation and bilinear transformation method designed to compare the results of the design and analysis)
