包含了使用matlab对声音信号进行时域和频域分析，加高斯噪声，并用高通、低通、带通滤波器进行滤波，并显示波形图。(Contains the sound signal using matlab time domain and frequency domain analysis, plus Gaussian noise, and high-pass, low pass, band pass filter to filter and display waveforms.)

ESPRIT是“Estimating signal parameters viarotational invariance techniques”的缩写，含义是“借助旋转不变技术估计信号参数”，它是由Roy[221等人于1986年提出的另一种基于子空间的DOA估计方法。 应用领域 　　侧向定位 信号处理 思想 　　ESPRIT的思想在于，将传感器阵列分解为两个完全相同的子阵列，两个子阵中每两个相对应的阵元具有相同的平移，即要求阵列具有平移不变性，每两个位移相同的阵元匹配成对。所幸的是实际中许多阵列满足这个条件，比如等距直线阵。(ESPRIT is "Estimating signal parameters viarotational invariance techniques" acronym, meaning "With ESPRIT estimation of signal parameters", it is by Roy [221, who in 1986 proposed DOA estimation method based on subspace another. Applications Lateral positioning signal processing Thinking ESPRIT thinking that the sensor array is divided into two identical sub-arrays, each of the two sub-arrays of two corresponding array element has the same translation, which requires an array with translation invariance, the displacement of each of the two identical arrays yuan matching pairs. Fortunately, many of the actual array satisfy this condition, such as equidistant linear array.)

D2D通信的资源分配算法。一对一复用，吞吐量最大化。(The resource allocation algorithm for D2D communication.)

说明：  这个是矢量控制，对三相异步电动机，仿真结果是正确的(This is vector control. For three-phase asynchronous motor, the simulation result is correct)

说明：  这是数模比赛里面的多雷达多目标数据融合代码，希望对大家有用~~(This is the Multi-radar data fusion multi-target code of Mathematical Model Competition,Hope to be useful~)

说明：   已知某控制系统结构图如下所示,要求设计校正环节G(s),使系统对于阶跃输入的稳态误差为零。使系统校正后的相角裕量γ≥45°，幅值裕量kg≥10db。(Known structure of a control system as shown below, links to design correction G (s), allowing the system to step input for the steady-state error to zero. The system after correction phase margin γ ≥ 45 °, the amplitude margin kg ≥ 10db.)
