Code to implement Back propagation network algorithm

该压缩包包括两个m文件，一个为IEEE推荐的UWB信道模型的matlab仿真程序，另一个为对应的RMS时延扩展计算，并附带了一个文档文件作说明。(The archive includes two m files, one for the IEEE UWB channel model recommended by the matlab simulation program, and the other for the corresponding calculation of RMS delay spread, and comes with a document file for instructions.)

1、观察采样引起的混叠。 2、判别离散时间系统的时不变性。 3、利用卷积计算信号通过FIR滤波器的输出，并观察输出信号的input-on暂态、input-off暂态和稳态阶段。 (One to observe the sampling due to aliasing. 2, determine the time invariant discrete-time systems. 3, the use of convolution calculation of the signal through the FIR filter output, and observe the output signal of the input-on transient, input-off transient and steady-state phase.)

说明：  正常情况下，电动机在matlab中simlink下的双PWM仿真图形( In normal condition, electric motor in matlab under simlink double PWM simulation graph )

里面有些常用的数值程序，如线性方程组的求解，插值，常微分方程的数值方法等等。(Inside some common numerical procedures, such as linear equations, interpolation, ordinary differential equations, numerical methods and so on.)

过滤距阵,算数平均值过滤误差值,文件读取.数组操作等.(Filter matrix, the average filter error count, the document read. Array, etc. operate.)

个慢跑者在平面上沿着他喜欢的路径跑步，突然一只狗攻击他，这只狗以不变的 速度跑向跑步者，狗的方向始终指向跑步者，计算并画出狗的运动轨迹（如需其他 条件，请自己假定）(A jogger in the plane running along the path of his favorite, a dog suddenly attacked him, the dog ran a constant speed runners, always point to the direction of the dog runners, calculate and draw the trajectory of the dog (For other conditions, at your own assumptions))
