基于matlab的4PSK的数字解调仿真(the 4-PSK demodulation using matlab)

说明：  读、写surfer文本的GRD格式的matlab程序，适合不需要插值的数据读写，比surfer自带的数据网格化功能处理的速度要快几十倍、甚至上百倍，可以处理大容量数据。(Reading and writing text surfer GRD format matlab program for reading and writing data without interpolation, the grid than the surfer' s own data processing capabilities several times faster, or even a hundred times, can handle large amounts of data.)

《MATLAB实用教程---控制系统仿真及应用》的配套光盘，不但便于读者使用，而且给任课老师提供了生成数量不限的 练习题的功能，便于因人施教。(" MATLAB tutorial--- practical control system simulation and application of" matching discs, readers not only easy to use, but also to the classroom teacher provides a unlimited number of exercises build functional, easy to teach from person to person.)

说明：  RBF径向基神经网络，用于销售额、销售量的预测(RBF Radial Basis Function Neural Networks for sales, sales forecast)

最优分割的基本思路是给定一个数据序列和分层数，通过搜索所有可能的划分方案，找到段内离差平方和的总和最小的一种方案作为最终划分方案。这里给出最优分割法的Matlab源程序(The basic idea is optimal partition for a given data sequence and hierarchical number divided by searching all possible solutions to find the segment and the sum of the squared deviations smallest division of a scheme as a final solution. This gives the optimal segmentation Matlab source)

相关函数法该方法先由序列估计出自相关函数R，然后对其进行傅立叶变换，得到功率谱估计。当延时和数据长度相比很小的时候可以有良好的估计精度。 (Correlation function method that the method is estimated by the sequence from a correlation function R, then its Fourier transform, the power spectrum estimation. When the length of delay and data can be compared to a very early age have a good estimation accuracy.)

在MATLAB中，进行FDTD仿真，二维电磁波传播。(In MATlab, FDTD Simulation for Electromagnetic Wave.)

OTSU法对图像进行二值化处理，并放回阈值(OTSU method of binary image processing, and back into the threshold)
