计算电波传播的一个MATLAB程序,用抛物线法求解的..还是初始阶段,共享一下.(terms of a radio wave propagation MATLAB procedures used parabola method .. or the initial stage, sharing about.)

各种滤波器的程序，并附有matlab的演示结果(Procedures for a variety of filters, together with the results of the matlab demo)

1. 基于simulink搭建一个QPSK发送链路，QPSK调制信号经过了瑞利衰落信道，观察信号经过衰落前后的星座图，观察信道特性。仿真参数：信源比特速率为500kbps，多径相对时延为[0 4e-06 8e-06 1.2e-05]秒，相对平均功率为[0 -3 -6 -9]dB，最大多普勒频移为200Hz。(1. Based on simulink structures, QPSK sent a link, the Rayleigh fading channel after the QPSK modulation signal, were observed before and after signal after the decline of constellation diagram, observation channel characteristic. Simulation parameters: the source is 500 KBPS bit rate, relative multipath time delay of [0 8 e 4 e- 06-06 e-05] 1.2 seconds, the relative average power is [0-3-6-9] dB, most of the doppler frequency shift is 200 hz.)

本MATLAB 例程用于脑电信号处理采用 CSP算法。(This MATLAB demo using CSP is intended for EEG signal processing)

这是一个基于simulink的无刷直流电机的仿真模型，可以得出很好的仿真效果(This is a brushless DC motor based on simulink simulation model, simulation results can be obtained very good)

Digital band-pass filter design, digital low-pass filter design, the digital noise signal is filtered out of the frequency band, spectrally move to restore the speech signal through a low pass filter

MATLAB随机数生成.M文件 里面有很多例子(MATLAB random number generator. M files)

matlab与vc混合编排的问题，可以得到有效解决，详细介绍后还有编码实现哦(Matlab and vc mixed scheduling issues can be effectively resolved After detailed There Coding oh)

用于实现灰度图像阈值分割的二维最大熵方法，matlab源程序(Used to achieve gray image threshold segmentation of the two-dimensional maximum entropy method, matlab source)

可以用来进行地震预测的matlab代码，直接模仿就可以用了(Can be used for earthquake prediction matlab code, you can use a direct imitation)
