psk31_9b_12a
PSK31 Model with Symbol Timing and Carrier Recovery(This model implements a communication standard known as PSK31. The transmit portion of the model can either synthesize the PSK31 signal, or use real world signals that were captured as Wave files.
The receiver features include: Automatic Frequency Control, Automatic Gain Control, Symbol Timing recovery with a fractionally spaced Farrow interpolator, Decision Directed Carrier Phase Lock Loop, dbsk or dqpsk demodulation with FEC.
References are provided in the Model.)

DSTATCOM_SVPWM_CONVER
1、基于Ip/Iq方法控制PWM整流器，实现有功无功解耦控制，实现直流电容的稳压控制。
2、分别采用滞环电流和电压空间矢量技术进行PWM调制
3、DSTATCOM无功补偿仿真验证
4、系统采用了在带有前馈解耦控制的基础上产生的电压电流双闭环控制结构，其中电压外环保证了稳定的直流输出，电流内环提高了电流的动态响应速度，并且这种控制方法使电流的相位和输入电压的相位保持一致。(1, based on Ip/Iq way to control the PWM rectifier to achieve the active and reactive decoupling control of DC capacitor voltage control. 2, respectively, using hysteresis current and voltage space vector PWM modulation technique 3, DSTATCOM reactive power compensation simulation 4, the system used in the decoupling control with feed-forward on the basis of the voltage and current double closed-loop control structure, in which voltage outer ring to ensure a stable DC output, current inner improve current dynamic response, and this control method makes the current phase and the phase of the input voltage is consistent.)

Welch法：Welch法对Bartlett法进行了两方面的修正：一是选择适当的窗函数w(n)，并在周期图计算前直接加进去，加窗的优点是无论什么样的窗函数均可使谱估计非负。二是在分段时,可使各段之间有重叠，这样会使方差减小。(Welch method: Welch method of Bartlett method amendments in two respects: First, select the appropriate window function w (n), and in the cycle before CALPHAD directly incorporated, plus the advantage of the window, no matter what kind of window function can be so spectral estimation of non-negative. Second, when in subparagraph can overlap between paragraphs, this would reduce the variance.)
