说明：  针对员工数目较多的公司，用于员工信息查询和工资计算(A relatively large number of companies for the employees, for employee information inquiries and payment of wages)

LMS算法及仿真实现，在等高线性能平面上绘制出了滤波器系数的运动轨迹和最优滤波器系数，以及错误概率的变化趋势。针对迭代次数变化和迭代步长变换分别作了相关讨论。(LMS algorithm and the simulation realization, in contour performance plane drawing out of the filter coefficient trajectory and optimal filter coefficient, and the change tendency of the error probability. According to the iteration times change and iterative step length transform the discussion related respectively. )

通信系统中有关于利用锁相环完成载波跟踪恢复的仿真功能(Communication system using phase-locked loop on the completion of the simulation function to restore the carrier tracking)

matlab程序： 计算机模拟思想计算概率模型(matlab program )

Matlab中的希尔伯特黄变换，很简单的三段程序，但是非常有用，这是注释版本(Matlab and Hilbert Transform，very useful)

该程序基本涵盖了OFDM-16QAM系统传输的全过程，除了调制解调外，有添加循环前缀，加窗的过程。生成图像有各个阶段的时域、频域图，以及发射前后的星座图。(This basically covers the whole process of OFDM transmission- 16 qam system, in addition to the modem, have add cyclic prefix, plus the window procedure. Generate the image at various stages of time domain and frequency domain graph, and before and after the launch of the constellation diagram.)

对三种pid控制方法进行比较仿真，从仿真结果可以看出彼此优劣，对学习PID及matlab仿真很有帮助。(Comparing simulation results from the simulation can be seen each other the merits of the three pid control methods, learning PID matlab simulation helpful.)

基于simulink单机无穷大系统，可进行暂态稳定计算。(Single machine infinite bus system based on simulink,Transient stability can be calculated.)

说明：  光伏并网逆变器仿真，包括直接功率控制和svpwm控制（基于PI）(Photovoltaic grid-connected inverter simulation, including direct power control and SVPWM control (based on PI))

this is the code to apply hilbert transform on a signal.
