基于matlab的脉压程序 线性调频信号的频谱 脉压信号的频谱(Matlab program based on pulse pressure Linear FM signal spectrum Pulse signal spectrum)

通过MATLAB中.m语言实现了标准大气模型(The standard atmosphere model is implemented by using matlab )

This simulation demonstrates the use of the PMSM in a closed-loop speed and current control on a 1.1 kW 3000 rpm industrial motor. A three-phase motor rated 1.1 KW, 220 V, 3000 rpm is fed by a PWM inverter. In this simulation, the whole system is built entirely with standard Simulink blocks (without resort to blocksets).

对通信中应用广泛的Kalman滤波进行matlab编程，并且得到的滤波效果比较理想，恢复的信号误码率可以达到很低。(Widely used for communications in the Kalman filter for matlab programming, and get the filter effect is ideal to restore the signal can reach very low bit error rate.)

matpower 工具箱,电力系统最优化工具箱，包括潮流计算和最优潮流等(matpower toolbox)

This program is to simulate the Rayleigh fading channels using a p-th order autoregressive model AR(p)

说明：  MATLAB答题卡识别（GUI，论文） 本课题为基于MATLAB的不变矩答题卡识别。可识别学号，学科，答案，并进行分数统计，以及判断是否及格。后台可设置标准excel答案。经过灰度变换形成灰度图像、二值化处理、图像滤波、边缘检测、hough变换等预处理。带GUI交互式界面。(Matlab answer card recognition (GUI, paper) This topic is based on MATLAB moment invariant answer card recognition. Can identify student number, subject, answer, and carry out score statistics, as well as judge whether pass. Standard excel answers can be set in the background. After gray-scale transformation, gray-scale image, binary processing, image filtering, edge detection, Hough transform and other preprocessing are formed. With GUI interactive interface.)

自适应LMS（最小均方误差）滤波器。（改变步长检查收敛速率）(Adaptive LMS (minimum mean square error) filter)

自相关信号检测仿真程序。在数据处理过程中，首先要检测信号的存在和大致位置。(Self-related signal detection simulation program. In the data processing, the first to detect the presence and approximate location of the signal.)
