to find decimation in signal processing

Generating Multivariate Gaussian RV

自己写的PCA降维算法，还有模糊k均值大家可以参考一下(Write their own PCA dimensionality reduction algorithm, and fuzzy k means we can refer to)

Uppal is a prototype verification tool to maodel and verify prototype

利用matlab研究使用维纳滤波器对语音信号去噪的例程(Using matlab studies using Wiener filter speech signals denoising routines)

说明：  常用的数值积分方法(特别是梯形、Simpson方法、和Romberg算法)，编制复合梯形公式，复合Simpson公式，Romberg算法的程序，数值积分方法的逐步精致化过程(Commonly used numerical integration methods (in particular, trapezoidal, Simpson method, and the Romberg algorithm), the preparation of composite trapezoidal rule, composite Simpson formula, Romberg algorithm procedure, numerical integration process of gradual refinement)

cdma系统matlab仿真程序，信道包括加性白高斯噪声，复合加性白高斯噪声，瑞利衰落，频率选择性瑞利衰落，双信道瑞利衰落。直扩调制，直扩解调。20段小程序，很不错。(cdma system matlab simulation program, channel, including AWGN, complex AWGN, Rayleigh fading, frequency selective Rayleigh fading, dual-channel Rayleigh fading. Direct Sequence Spread Spectrum modulation, demodulation DS. 20 small procedures, is pretty good.)

关于线性调频信号，输出它的时域、幅度谱、相位谱(Linear FM signal, the output of its time-domain amplitude spectrum and phase spectrum)

说明：  matlab振动试验数据分析，信号获取：测量获取设备的信号（振动、转速、过程参等）。信号分析：从信号中提取反映设备运行状态和故障的特征值。故障诊断：根据信号特征信息，对故障进行诊断（专家诊断、智能自动诊断）和预测(Matlab vibration test data analysis, signal acquisition: Measurement and acquisition of equipment signals (vibration, speed, process parameters, etc.). Signal analysis: extract the characteristic value of equipment running state and fault from the signal. Fault diagnosis: fault diagnosis (expert diagnosis, intelligent automatic diagnosis) and prediction according to signal characteristic information)
