ACO_TSP

在matlab编译环境下，下实现迪杰斯特拉算法。 程序鲁棒，速度较快。(the implementation of Dijstla algorithm)

4psk的matalab仿真系统，对研究很有用途(Matalab the 4psk simulation system is the use of research)

fsk simulation in Matlab

频率调制和解调 频率调制是将消息信号的积分作为相位，也就是用消息信号去调制频率 ( Of the frequency modulation and demodulation frequency modulation is the integral of a signal of the message as the phase, that is, with the message signal to the modulation frequency)

matlab编写的调整svm参数的程序，其中cross是主程序，另两个是自己编写的svm核函数，如果要用matlab自带的核函数就把-t的值改成2即可。Ytrain是标记矩阵，Xtrain是特征矩阵，都由用户自己导入。可利用k倍交叉验证来选择最优的c参数。k可自行更改。(svm matlab prepared to adjust the parameters of the program, which cross the main program, and the other two are themselves prepared svm kernel function, if you use the value of the kernel function matlab own put-t can be changed to 2. Ytrain is labeled matrix, Xtrain is characteristic matrix, imported by the users themselves. K-fold cross-validation can be used to select the optimal c parameter. k can make changes.)

assk,fsk,psk,dpsk的matlab仿真程序(assk, fsk, psk, dpsk the matlab simulation program)

卡尔曼滤波仿真算法！！！经典的哦！！！！！！！！(Kalman filter simulation algorithm. ! !)

本文实现了09年CVPR的文章Linear Spatial Pyramid Matching using Sparse Coding for Image Classification(This package contains the Matlab codes implementing the ScSPM algorithm described in CVPR 09 paper "Linear Spatial Pyramid Matching using Sparse Coding for Image Classification". )

主要描述了单模光纤和多模光纤耦合对接的模场分布情况(Describes the mode field distribution of single-mode fiber and multimode fiber coupling docking)

一、 本程序采用16QAM调制方式，对一串2进制信源进行调制，采用（7，4）循环码对信源做信道编码，用升余弦滚降函数进行基带调制，再调到高频信道；在信道上加入高斯白噪声，运用匹配滤波器解调，画出解调星座图，运用最小欧氏距离译码判决，再对信号进行信道解码，画出采用信道编码技术和不采用信道编码技术的误比特率图。(First, this program uses 16QAM modulation mode, for a string of two binary source is modulated, using (7,4) cyclic code of the source-channel coding to do with a raised cosine roll-off function for base-band modulation, and then transferred to a high frequency channel in the channel by adding Gaussian white noise, the use of matched filter demodulation, demodulation constellation plot, using the minimum Euclidean distance decoding decision, and then right channel signals, decoding, channel coding techniques used to draw and non- channel coding techniques using bit error rate plans.)
