PSO算法，在实验室matlab7.9环境运行过，主要是做LED灯光强度试验的(PSO algorithm running in the laboratory, matlab7.9 environment, mainly to do LED light intensity test)

刘金坤编写的智能控制一书中的程序代码，调试通过的！(Smart Liu Jinkun a book written control program code, debugging through!)

详细讲述了直接序列扩频差分锁相环的文章，包含具体的算法结构，并附有仿真结果。(A novel differentially coherent delay-locked loop(DCDLL) for accurate code tracking is proposed for direct sequence spread spectrum systems. Due to the use of the differential decoder and exactly one correlator, the proposed scheme avoids the problems of gain imbalance. The tracking error variance is derived by linear analysis. When the proposed DCDLL scheme is applied in ranging with additive white Gaussian noise (AWGN) channel, the performance of the proposed DCDLL scheme is about 1.4 dB better than that of one-correlator tau–dither loop (TDL), and near that of noncoherent DLL.)

入门基本操作,给大家一个简单的介绍，以此来了解matlab(Getting Started Basic Operations)

数字水印matlab程序，只是简单的svd跟最简单的置乱方法Arnold的应用。没有用到小波算法。上传的dwt_svd_GUI.rar是完整的数字水印算法，用的是混沌加密。(Matlab digital watermarking process, with the svd simply the easiest way to Arnold scrambling applications. Wavelet algorithm is not used. From the dwt_svd_GUI.rar is a complete digital watermarking algorithm, using a chaotic encryption.)

说明：  基于Matlab的支持向量机参考简单代码程序(Matlab based support vector machine reference simple code program)

采用一种新的方法仿真Nakagami模型(Nakagami model using a new method of simulation)

使用FR共轭梯度法求解无约束问题 输入包括初始点，目标函数和梯度 输出包括最优点和最优解，还有迭代次数(Use FR conjugate gradient method for solving unconstrained problems including initial entry points, the objective function and the gradient of the output, including the advantages and the most optimal solution, as well as the number of iterations)

激光雷达是以发射激光束探测目标的位置、速度等特征量的雷达系统。从工作原理上讲，与微波雷达没有根本的区别：向目标发射探测信号(激光束),然后将接收到的从目标反射回来的信号(目标回波)与发射信号进行比较.本程序为FMCW激光雷达matlab程序，包括调频非线性校正等(Laser emitting a laser beam radar detection is the target position, velocity, volume and other characteristics of the radar system. From the working principle, and there is no fundamental difference between the microwave radar: transmitting to the target detection signal (laser beam), then the received signal reflected from the target (target echo) is compared with the transmitted signal, after appropriate treatment , you can get information about the target, such as the target distance, direction, altitude, speed, attitude, and even the shape and other parameters to the aircraft, missiles and other target detection, tracking and identification. This program is FMCW laser radar matlab procedures, including FM nonlinear correction.)
