CDMA系统中随机扰动蚁群多用户检测算法(CDMA system in random disturbance on ant colony algorithm for multi-user detection)

这是我们第一次实习的MATLAB的答案，希望对大家有所帮助，呵呵，你们也认为呢？希望我们共同建设好这个网站，我们需要她！(This is the first time we attachment MATLAB answer, and I hope to help you, Oh, you think? We hope to build a good web site, we need her!)

是用于模式识别中的一种数据采样方法，此方法是把数据按一定的比例分为训练数据和测试数据。(for pattern recognition of a data sampling methods, This method is data by a certain percentage into training data and test data.)

Generates a D-optimal design of experiments.

用模最大值法提取小波脊，该例中又两条小波脊，所以是多脊提取。同时又施加惩罚函数，控制lamda的值，可以得到较为平滑的小波脊。( using maximum modulus extract wavelet ridge, the case has two wavelet ridge, it is a multi-ridge extraction. At the same time to impose the penalty function to control the value of lamda,the extracted ridge can be relatively smooth .)

用Matlab来实现Kalman滤波器,此种可用于卫星导航系统，还可用于其它对踊跃比较严格的场合(using Matlab to achieve Kalman filter can be used for such a satellite navigation system can be used for other more enthusiastic strict occasions! !)

随机反馈控制matlab 程序，针对unstable 带poisson jump 系统，设置反馈控制，来稳定化unstable 随机系统(using state feedback control to stabilize an unstable stochastic jump system )

录制自己的一段语音，时间控制在15秒到30秒左右；利用wavread函数对自己的语音进行采样，记住采样频率。 （1）画出原始语音信号的时域波形，而后以1秒为间隔，求出每秒数据的功率谱。 （2）根据语音信号特点，分别设计FIR及IIR滤波器，分别画出滤波器幅频和相频特性曲线。用设计的滤波器对信号滤波，画出滤波后时域波形。用sound函数回放语音信号。 （3）求出特征频段语音信号随时间变化的曲线（每间隔0.05秒求一次功率谱）。 (Record your own voice for some time (15 seconds to 30 seconds) use wavread function of the voice samples, remember the sampling frequency. (1) Draw the original speech signal in time domain waveform, and then to 1 second intervals, the data obtained power spectrum per second. (2) According to the voice signal characteristics, FIR and IIR filters were designed, namely to draw the amplitude and phase frequency characteristic curve. With the design of the filters on the signal filtering, to draw the filtered time-domain waveform. Playback with sound function of the speech signal. (3) Find the characteristic band speech signal curve over time (0.05 seconds intervals seeking a power spectrum.))
