modulation

说明：  比较了FFT算法和低通滤波器在去除噪声中的作用(compared the FFT algorithm and low-pass filter to remove noise in the role)

Heed Protocol for WSN

曲线、曲线修改、坐标轴范围及坐标轴修改等源代码(Curve, the curve changes to the scope and coordinate axis coordinate axis modify the source code, etc.)

编写了利用MATLAB计算任意桁架的静力分析，得到各杆的应力和各结点的位移，并画出变形前后的桁架图(The static analysis of arbitrary truss is made by using MATLAB, the stress of each rod and the displacement of each node are obtained, and the truss diagram before and after deformation is drawn)

自己编写的MATLAB程序，原创，希望有用(I have written MATLAB program, originality, I hope useful)

有源电力滤波器设计，三相三线，PR控制，电压空间矢量控制(active filter ,PR control,svpwm control)

用matlab产生仿真BPSK信号，并对BPSK信号采用FFT进行频谱分析。(Simulation of BPSK signals generated by matlab, and BPSK signals using FFT spectral analysis.)

This chapter contains sample programs for determining capacity. The reader is advised to go through the coding. The file "capacity_water.m" is for measuring the waterfilling capacity. It should be made to work with a file similar to "capacity_plot_main.m". The latter file deals with all the other capacity plots given in the book in Chapter 2. All programs are verified with MATLAB versions 6.0 and above with signal processing and communications toolboxes.(This chapter contains sample programs for determining capacity.
