一类Bessel方程Matlab程序源代码

说明：  matlab开发环境，Broyden迭代法解非线性方程组，其中的M文件(matlab development environment, Broyden iteration method for solution of nonlinear equations, in which M-file)

用matlab的GUI做的一个数字信号处理系统，选择输入信号波形及频率，进行滤波、频域分析等等。(Using matlab to do the GUI of a digital signal processing system, select the input signal waveform and frequency for filtering, frequency domain analysis and so on.)

说明：  国外编写的仿真程序，利用Simulink软件对波音747飞机进行仿真，很有参考价值(The preparation of the simulation program abroad, the use of Simulink software for Boeing 747 aircraft simulation, useful reference)

基于拉普拉斯塔型分解图像融合算法,采用matlab实现,算法用三层分解(Lapulashida-based decomposition algorithm for image fusion using Matlab realized, with the three-tier decomposition algorithm)

该代码为多频外差四频相移的原理程序，开发环境为MATLAB,可以帮助初学者快速了解外差法的原理。(The code on multiple frequency heterodyne principle of four frequency phase shift process, development environment of MATLAB, can help beginners to quickly understand the heterodyne principle. )

QPSK的锁相环程序，在MATLAB环境下编写的，用来进行QPSK通信系统的仿真和实际信号载波同步的提取。(QPSK PLL program, written in MATLAB environment, is used for the simulation of QPSK communication system and the extraction of actual signal carrier synchronization.)

this code realize the two dimention esprit algorithm

直接扩频序列的频谱分析，从DSSS信号的产生到接收，不错的直接扩频序列分析函数，以测试通过，有图产生(Spectrum analysis of direct sequence spread spectrum, from DSSS signal to produce received a good direct sequence spread spectrum analysis function to test, there are plans to produce)

FFT算法的实现，MATLAB仿真，验证，模拟(FFT SUANFA DE SHIXIAN ,FANGZHEN)

说明：  卡尔曼滤波器的滤波性能。被控对象是二阶传递函数，采用M语言。该滤波器对控制干扰和测量噪声具有良好的滤波作用。(The performance of Kalman filter)
