说明：  MATLAB的瑞利衰落信道仿真，针对服从瑞利分布的多径信道进行模拟仿真，加深对多径信道特性了解。(Channel Emulation of Rayleigh fading by using MatLab,which is aimed at the Multipath Propagation channel that obey Rayleigh distribution, so it could be furthered comprehension of characteristic on the Multipath Propagation channel.)

用BP网络逼近某曲线函数，在神经网络中邮广泛的应用 是系统辨识的基础。 通过反馈来不断的调整系数，限制了最大循环次数 防止进入死循环，当然如果想要得到更精确的系数可以增大循环次数。 (Using BP network function approximation to a curve, mail is widely used in neural network is the basis of system identification. Through feedback to constantly adjusted factor, limit the maximum cycle times to prevent into dead circulation, and of course if you want to get a more accurate coefficients can increase the cycles.)

最近邻插值,在图像处理中，对变换后的图像进行插值(Nearest Neighbour interpolating)

To support wireless communication : MIMO

matlab实现的FSK调制解调程序，请大家使用，并提出建议。谢谢(matlab implementation of the FSK modulation and demodulation process, let us use, and make recommendations. Thank you)

说明：  系统辨识中的各种辨识算法：如最小二乘法、递推最小二乘法、广义最小二乘、变遗忘因子递推算法等。(System Identification of identification algorithm : if the least-squares method, recursive least squares method, generalized least squares, changing the forgotten factor algorithm.)

说明：  用Floyd算法设计的最小费用最大流，求最大流时，用的是标号算法(Floyd algorithm design with the minimum cost maximum flow, for maximum flow, the algorithm is labeling)

q730是模拟低通转换为数字低通.q731是切比雪夫滤波器设计，q732椭圆带通数字滤波器的设计，其中用的是ellipord函数(q730 is converted to analog low-pass digital low-pass. q731 is a Chebyshev filter design, q732 elliptical band-pass digital filter design, which is used in a function ellipord)

说明：  对一个小球的运动模拟，可以很好地模拟其轨迹，界面清晰，操作简单(A small ball of motion simulation that can simulate its trajectory, clear interface, easy operation)
