说明：  16QAM的数字通信系统的仿真，包括调制解调，上下变频，加入了高斯白噪声，并且每个步骤都生成相应的图形(16QAM digital communication system simulation, including the modulation and demodulation, frequency conversion from top to bottom, by adding a Gaussian white noise, and each step to generate the corresponding graphics)

Matlab code for Create a domain x for the mixture

通过matlab实现czt频谱细化算法，绘制图形与fft方法进行比较(By thinning algorithm matlab realize czt spectrum, graphing methods were compared with fft)

对目标图像处理进行后，可以对目标进行追踪，卡尔曼滤波模型是目标追踪中常用的代码(After image processing, the target can be tracked. Kalman filter model is a common code in target tracking.)

用于仿真正负线性调频信号在同时极化测量中的性能(Simulation of positive and negative for the chirp signal at the same time measuring the performance of polarization)

matlab中的mapminmax函数，可以直接使用(matlab' s mapminmax function, can be used directly)

DTMF goertzel function, it is really helpful for other beginners who want to do the DTMF

message regarding disperssion effect in communication

电力线噪声模型的仿真模型，该模型还建立了其多径情况下的噪声(Power line noise model simulation model, which also established its case multipath noise)

分析橡胶挤出到人工分剪过程中的运动，以适应企业所生产所有规格橡胶为目标；以台达SV2型号PLC为控制核心，采用惠斯通电桥压电式传感器实时采集橡胶重量变化；针对现场加工环境中产生的振动干扰，并分析称重传感器采集到的称重信号；针对分剪系统响应速度与橡胶挤出速度匹配问题导致的不同挤出速度下误差的分布不同，且随着挤出速度的增大导致所分剪橡胶误差也增大的问题，(The movement of rubber extrusion to artificial shearing process is analyzed in order to adapt to the rubber of all specifications produced by the enterprise. Taking the delta SV2 model PLC as the control core and using the Wheatstone bridge piezoelectric sensor to collect the change of rubber weight in real time, the vibration interference produced in the field processing environment and the analysis of the weighing sensor are analyzed. The set of weighing signals; the distribution of errors at different extrusion speeds caused by the matching of the response speed of the shear system to the rubber extrusion speed is different, and the error of the shear rubber increases with the increase of the extrusion speed.)
