基于MATLAB的BP神经网络设计的源代码(jiyuMATLABdeBP shenjingwangluoyuanchengxu)

用于均衡DPSK信号的JD-MLSE算法，为matlabb程序，输入DPSK解调的两路信号，判决得到所需的bit序列，并计算误码率(It s used for electronical equalization based on joint-decision maximum likelyhood estimation (i.e. JD-MLSE).)

说明：  本程序是对PN序列的自相关性的仿真，希望能对各位有所帮助(This procedure is the autocorrelation of PN sequence simulation, hope you can help)

QAM调制信号生成，可针对多种类型成型滤波器(QAM modulation signal generation can be formed for a variety of types of filter)

用matlab画圆( create circle)

用MATLAB实现世界地图的绘制，包括二维、三维等方式以及图片的叠加(Using MATLAB to achieve world map drawing, including the two-dimensional, three-dimensional image of the stack, etc., and)

批量时域变换为频域处理地震波，循环操作，速度快(Batch processing time domain into frequency domain of seismic wave)

本实验将使用MATLAB 7.0软件分别对20钢的离子渗碳和气体渗碳过程进行模拟，渗碳时间分别为1h、2h、8h、20h，渗碳温度分别为1203K、1223K、1273K、1323K。对20钢的其中一面进行一维气体渗碳，设该扩散系数和界面传递系数均与渗碳浓度无关，对渗碳厚度、渗碳速度、渗碳量和渗碳时间、渗碳温度的关系进行模拟。(In this study, using MATLAB 7.0 software 20 steel ion carburizing and gas carburizing process simulation, carburizing time were 1H, 2H, 8h, 20h, carburizing temperature of 1203K, 1223K, 1273K, 1323K. 20 steel one side of a one-dimensional gas carburizing, set the diffusion coefficient and interface transfer coefficient has nothing to do with the concentration of carburizing, the relationship of the thickness of the carburizing, carburizing speed, carburizing and carburizing time, carburizing temperature simulation.)

自己写的matlab源码，用于球信号包络，非常好用，简单可靠。(Write their own Matlab source code for the ball signal envelope, very easy to use, simple and reliable.)

说明：  预测编码的部分函数，如需使用还需另外编写部分函数(Predictive coding part of the functions needed to prepare the part for the use of function)
