AM_DSB_SC_Modulation

说明：  比例导引法的MATLAB，程序，希望大家多侃侃(matlab)

通过一系列教学实例，帮助学生很好的理解matlab中的符号运算实现微分、积分（定积分与不定积分）、极限、级数、绘图等常用功能，几乎可以推导高数中的绝大部分公式，也可用于理论公式推导。(Through a series of teaching examples to help students a good understanding of symbolic computation matlab achieve differentiation, integration (with the definite integral indefinite integral), ultimate, series, graphics and other commonly used functions can be derived almost most of the high number of formulas can also be used to derive theoretical formulas.)

自己写的UKF滤波程序，使用2n+1Sigma点采样(UKF filter written by myself, using 2n+1 Sigma-point sampling)

PSK 调制方式的解调第一部分，解调过程建模和参数设置(PSK demodulator of part 1)

信号与系统 信号与线性系统分析 matlab 编程研究(matlab signal and linear analysis)

时兴的前推回代算法程序，可用于求解辐射状配电网三相潮流。(Forward-Backward Sweep algorithm for three-phase load-flow analysis of radial distribution systems.)

二维码编码解码器源码，可以实现扫描二维码，使用很方便(Dimensional code codec source code, you can achieve scan two-dimensional code, very easy to use)

说明：  声音频率的转换声音频率的转换声音频率的转换(Sound frequency conversion)

本程序涵盖预测控制模糊控制等多个知识点运行效果良好(This procedure covers the fuzzy control, predictive control point running well over knowledge)

采用平面梁单元计算两铰抛物线拱的在初始条件下自由振动，并对时程曲线结果进行FFT变换(Calculated using plane beam element in two-hinged parabolic arch of free vibration under initial conditions, and the results of time-curve FFT)
