本程序是基于ridgelet和小波的图像分割，内附有程序运行的图像(This procedure is based on the Ridgelet and wavelet for image segmentation, enclosed to run image)

这是pcnn用于边缘检测的matlab源代码，希望对大家有用。(edge detection for the Matlab source code, we hope that the right useful.)

关于脉冲信号的matlab程序。包括单边衰减指数信号，正弦信号，抽样信号，矩形脉冲信号等。(matlab program about pulse signal.)

本程序模拟了一个2DPSK发送和接受的完整过程，差分编码采用模2加的方式得到，本次实验采用的是相移键控的方法得到发送信号，2DPSK信号最常用的解调方法有两种，本次实验采用的是极性比较法，先通过2PSK相干解调器，再经过码（反）变换器得到基带信号。 (This program simulates a 2DPSK sending and receiving complete process, differential coding is completed by modulo-2 addition； the experiment using the phase shift keying method to send signals.this experiment is the polarity comparison method,firstly go through the 2PSK coherent demodulator and then pass through code (trans) converter to obtain a baseband signal.)

matlab 贮存轮 数模学习用。！！！！！(matlab the storage round of digital-to-analog learning. ! ! ! ! !)

OFDM下行的仿真1、产生要传输随机数； 2、进行调制； 3、串并转换； 4、进行IFFT操作（代码中有用到共轭对称向量的IFFT为实数进行简化计算）； 5、增加循环前缀； 6、并串转换； 7、输出前滤波； 8、增加信道噪声（加性高斯白噪声）； 9、接收端串并转换； 10、去除循环前缀； 11、进行FFT变换； 12、信号解调； 13、误比特率计算； (OFDM downlink simulation 1, have to be transmitted random number 2, the modulation 3 series and transforms 4, the IFFT operation (code useful to conjugate symmetric vector of the IFFT of real numbers to simplify calculations) 5, the increase in circulating prefix 6, and string conversion 7, the output before the filter 8, increased channel noise (additive white Gaussian noise) 9, the receiver string and conversion 10, removal of cyclic prefix 11, the FFT transform 12 , the signal demodulation 13, bit error rate )

说明：  matlab多项式的应用在趋向拟和的数据的拟和方面应用非常广泛(Matlab polynomial trend in the application and data to the application and to be very broad)

ML的方法在ofdm中的应用，是最大似然在ofdm中的仿真(ML method ofdm application is the maximum likelihood in the simulation ofdm)

说明：  另外一种旋转式永磁同步电动机空间矢量PWM控制算法，可以作为比较参考。(Another permanent magnet synchronous motor rotating space vector PWM control algorithm can be used as comparison reference.)

MODULATOR MIMO IS VERY GOOD REFERENCE
