matlab FEM source code for beam analysis

这是用于电火花机床加工控制参数优化的一个多目标遗传算法的matlab程序，自己原创，分享出来和大家交流。 (It is used for electric discharge machining control parameters optimization of a multi-objective genetic algorithm matlab program, their own originality, share them and everyone exchanges.)

现在通信系统仿真中的锁相环技术，给出仿真程序以及后处理(Communication system simulation is now PLL technology, the simulation process and post-processing)

该模型描述的是zeta变换器。控制方式为电感电流控制。分析在一组参数下的非线性现象，画出相图，时域图，观察从周期一到周期二最后进入混沌状态(The model describes the zeta converter. Control mode for inductance current control. Analysis in a group of parameters of the nonlinear phenomenon, draw the phase diagram, time domain chart, observation from cycle to cycle a second finally into chaotic state )

关于紫外光语音通信系统的大气信道的仿真程序（MATLAB实现）(UV-voice communications systems on the atmospheric channel simulation program (MATLAB implementation))

说明：  该程序是用matlab语言实现的关于瑞利信道多径传输的多谱勒效应的描述(that the procedure was used Matlab language on the Rayleigh Channel multipath transmission of the description of Doppler effect)

power system particle swarm optimization

说明：  与连续信号的解调相比，短时突发信号持续时间短，不适用性能良好的反馈环路算法，需要使用前向幵环算法。与一般突发信号相比，短时突发信号没有训练序列、同步头等辅助信息，所有参数需要利用有限的数据估计。与合作通信相比，盲接收信号参数的初始偏差较大，估计范围小的算法不适用。每个突发包的数据有限，解调过程不允许丢失任何符号。(Compared with the demodulation of continuous signal, short burst signal has a shorter duration and is not suitable for the feedback loop algorithm with good performance. Forward loop algorithm is needed.)
