集群通信随机接入仿真，主要是针对集群用户接收与普通用户接收的对比（直方图），集群用户正确接收率、普通用户接收率，总的误判率。(Cluster communication random access, cluster users and ordinary users access contrast (histogram), cluster users receive the accuracy and ordinary users receive the accuracy rate of miscarriage of justice problems.)

一种具有提示功能的文本框，可以根据实际使用进行重新，具有很好的参考价值(A text box with prompts that can be re-based on actual use, a good reference value)

说明：  MATHCENTRER下载的雷达杂波仿真系统，非常有参考意义(MATHCENTRER download of radar clutter simulation system, meaning a very good reference)

本文利用软件相移技术得到相互正交的参考正弦波信号；通过互相关算法，完成了软正交矢量型LIA相关器的具体实现；利用该方法实现了对微弱信号幅值和相位的检测，有效地抑制干扰，减少了硬件电路成本。通过Matlab仿真，验证了该算法具有一定的优越性。(In this paper, the software technology is orthogonal to the phase shift of the reference sine wave signal through cross-correlation algorithm to complete the implementation of soft orthogonal vector LIA correlator achieved using this method for detecting a weak signal amplitude and phase, effectively suppress the interference and reduce the cost of the hardware circuit. By Matlab simulation show that the algorithm has certain advantages.)

灰色预测方法的特点表现在：首先是它把离散数据视为连续变量在其变化过程中所取的离散值，从而可利用微分方程式处理数据；而不直接使用原始数据而是由它产生累加生成数，对生成数列使用微分方程模型。这样，可以抵消大部分随机误差，显示出规律性。(The characteristics of the grey prediction method are as follows: First, it regards the discrete data as the discrete value of the continuous variable in its change process, so that the differential equation can be used to process the data; instead of using the original data directly, it generates the cumulative generation. Number, using a differential equation model for generating a series. In this way, most of the random errors can be offset, showing regularity.)

对于过热器的温度控制，采用串级PID的控制方法，进行温度控制，在有扰动的情况下，控制效果比较理想。(For superheater temperature control, cascade PID control method is adopted to carry out temperature control. Under disturbance, the control effect is ideal.)
