这是一份MATLAB基础课件，由于我也是初学者，这部课件讲的很浅显，但比较适合初学者对MATLAB所有功能的一个初步了解内容包括涵数值数组及其运算， M文件和面向对象编成， 字符串数组， 符号变量， matlab 绘图 及 Simulnk动态仿真。以及两个基本浅显的程序题。此为第 4章。(This is a basic MATLAB courseware, because I am also a beginner, this software is very simple-speaking, but more suitable for beginners of all the features of MATLAB, a preliminary understanding of the content including the Han and its numerical array computing, M documents and for object into string array, variable symbols, matlab graphics and dynamic simulation Simulnk. As well as the two basic procedures for simple questions. This is Chapter 4.)

Matlab代码实现了一个调制的GUI界面，同时实现了ASK, OOK, BPSK, QPSK, 8PSK调制算法的源代码。以图像形式展示了各种调制算法的实际运行结果。 (Matlab code implementation of a modulation GUI interface, at the same time achieve the ASK, OOK, BPSK, QPSK, 8PSK modulation algorithm source code. Image form a variety of modulation algorithm to display the actual results.)

毕业论文 基于LSB图像水印系统设计matlab实现(Graduation thesis matlab based on LSB image watermarking system design)

matlab simulink四旋翼模型，输入为四个电机的电压值，输出为对应的姿态角以及姿态角速度和三个方向的线加速度(Four rotor model, the input voltage is four value of the motor, the output is the corresponding attitude angle and attitude angular velocity and direction of three linear acceleration)

说明：  QPSK仿真，通过高斯信道，瑞利信道进行调制解调，计算误码率，绘制星座图(QPSK simulation, through the Gaussian channel, Rayleigh channel modulation and demodulation, calculate the bit error rate, draw constellation)

遥感地图多项式校正,用matlab实现，本来还想写共线性校正的，还没写好，写好后上传(the polynominal correction of remote sensing map)

扩频通信，从电磁波利用来看，与一般现有的常规通信方式完全不同。扩频通信利用伪随机编码把信息数据（窄带信号）的频谱进行扩展，形成宽带的低功率谱密度信号发射，使用不同的伪随机序列编码，不同通信用户可在同一频段、同一时间工作，互不影响或干扰极小地进行通信。(Spectrum, from the electromagnetic waves used term, and the general existing conventional means of communication is entirely different. Spread spectrum communication using pseudo-random code to the information data (narrowband signal) to extend the spectrum, the formation of low-power spectral density broadband signal transmission, using different pseudo-random sequence of coding, different communication users at the same frequency band, at the same time work, mutual does not affect or interfere with a very small way to communicate.)

一种系统辨识方法，基于辅助模型对输出误差系统进行未知参数辨识(AM_FG.m for the output error models)

Cosinor analysis uses the least squares method to fit a sine wave to a time series. Cosinor analysis is often used in the analysis of biologic time series that demonstrate predictible rhythms. This method can be used with an unequally spaced time series. Follows cosinor analysis of a time series as outlined by Nelson et al. Methods for Cosinor-Rhythmometry Chronobiologica. 1979.
