学习期间老师布置的作业，一些simulink基础的DSP应用。英国Strathclyde大学的课程教学。(Studying teacher assignments, some simulink-based DSP applications. Strathclyde University, UK Teaching.)

The function applies the Madsen method for Doppler Centroid estimation. The input are: 1) the raw data, the parameter of the distance between samples in azimuth to be correlated and the PRF (Pulse repetition frequency)

GNSS软件接收机，源自《软件定义的GPS和伽利略接收机》书中配套程序，做过修改，在原有程序框架下使用了2阶锁频环辅助3阶锁相环(The GNSS software receiver, derived from GPS and Galileo receiver of software defined supporting program in the book, modification, the original application framework use 2 order frequency locked loop aided third-order phase-locked loop )

Model Predictive Control based on linear models is widely used in the process Industry.

利用Matlab生成GPS C/A 码的基带信号。 （1）产生卫星PRN 号码为“5”的一组C/A 码； （2）循环生成25 页的导航数据，GPS 时间可填入一固定的已知数值； （3）生成C/A 码扩频信号，每个C/A 码码片给出4 个采样数据； （4）基带信号采用方波信号，电平为0 和1，占空比为50 ％， 不加入噪声，进一步生成某个特定的中频信号(The baseband signal is generated using Matlab GPS C/A code. (1) generate satellite PRN number " 5" is a set of C/A code (2) loop generates 25 navigation data, GPS time can be filled with a fixed known value (3) generated C/A code spread spectrum signals, each C/A code chip sample data is given 4 (4) a baseband signal using a square wave signal with a level of 0 and a duty cycle of 50 , the noise was not added, and further generates a a specific frequency signal)

说明：  BLDCM的simulink模型，电流、转速双闭环控制的无刷直流电动机系统，电机模块是自己封装而成的不是用的永磁同步电动机或者自带的BLDCM，所涉及的三个程序也有展示。(The model of BLDCM, the BLDCM system with double closed-loop control of current and speed,and the motor module is a self packaged permanent magnet synchronous motor or BLDCM, and the three programs involved are also shown.)

基于欧几里得距离的聚类分析，未来线路预测,分析误差,阐述了负荷预测的应用研究。( Clustering analysis based on Euclidean distance, Future line prediction, error analysis, It describes the application of load forecasting.)

采用TLS-ESPRIT算法，进行空间阵列信号的频率估计(With TLS-ESPRIT algorithm to estimate the signal frequency space array)

运用simulink软件，搭建最优控制理论的模型，能运用于简单的仿真环境。(Using simulink software, build the model of optimal control theory can be applied to a simple simulation environment.)
