Simulation

说明：  压电电缆 技术资料，现在 路考主要 材料(Piezoelectric cable technical data, the main material is a road test)

wireless matlab prog like as bpsk ber.

power_voltmeasure.rar,功率电子领域matlab仿真文件，已经验证过，程序运行正常(power_voltmeasure.rar,Power electronics field matlab simulation file, has already been verified, the normal operating procedures)

近似熵是一种衡量衡量非线性时间序列复杂性的非线性动力学分析方法，其物理意义 为熵值越大，时间序列的自我相似性越低，序 列越复杂，反之序列自我相似性越高；并且样 本熵对于序列长度依赖弱，仅需较短的数据就 能够得到稳健的熵值，同时其计算不需对数据 粗粒化，具有较好的抗干扰能力 (Approximate entropy is a measure to measure the complex nonlinear dynamics of nonlinear time series analysis method, the physical meaning of entropy value is larger, the lower the self-similarity of the time series, the more complex the sequence, whereas sequence of self-similarity the higher and the sample entropy weak dependence for the length of the sequence, only shorter data can be healthy entropy value, calculated without data coarse-grained, with good anti-jamming capability)

共上载5个源码，其中c语言c_matrix为矩阵类，可以实现几十种矩阵运算；其它四个为matlab程序，用于生各种杂波的程序(Upload a total of 5 source code, in which c language for c_matrix matrices can be achieved dozens of matrix operations the other four for the matlab program for Health and a variety of procedures Clutter)

输出量通过回路使得占空比D增加或减少，以控制电压的输出或减少，从而达到最大功率点(Output circuit by which the duty ratio D is increased or decreased to reduce the output or control voltage to achieve maximum power point)

说明：  增广路的程序 挺简单的 大家看说明就能看懂 (widen the road quite a simple procedure you can understand looking)
