在矩阵或者二维图像中画一个圆,没有丢失的像素点 (Draw a circle in a matrix/image)

1.原始信号A，通过信道受噪声污染后的信号q，然后分别经过均衡器ZF（MMSE）得到信号U，可以画出U的分布图 2.分别应用LMS,SATO,CMA算法得到U。（其中包括最佳延迟、均方误差的计算）所有结果均以图像形式显示。(1. The original signal A, subject to noise pollution through the channel after the signal q, and then through the equalizer, respectively ZF (MMSE) receive the signal U, the distribution of U can draw Figure 2. Were applied LMS, SATO, CMA algorithm to be U. (Including the best delay, mean square error terms) all the results are displayed in graphic form.)

关于LMS算法的几种仿真，层层递进，加大算法复杂性以达到更好的效果，程序中包含几种算法的对比。(Simulation of several on the LMS algorithm, progressive layers, increase the complexity of the algorithm in order to achieve better results, the program contains a comparison of several algorithms.)

ParInfoGain - Computes parallel information gain and gain ratio in Matlab using the Matlab Parallel Computing Toolbox or the Distributed Server (if available) Information gain is defined as: InfoGain(Class,Attribute) = H(Class) - H(Class | Attribute) Gain ratio is defined as: GainRatio(Class, Attribute) = (H(Class) - H(Class | Attribute)) / H(Attribute). ...where H is the entropy, defined as - sum(i=1 to k) pi log2 pi

viterbi译码算法，可以对卷积码进行解码。通信类的朋友知道的。。。(viterbi)

这个程序就是最基本的粒子群优化算法程序，用Matlab实现，非常简单(This program is the most basic particle swarm optimization algorithm, using Matlab to achieve, is very simple)

说明：  有偏卡尔曼滤波器可以用来消除无线定位中的非视距误差,本程序加入了非视距检测模块，对于NLOS使用有偏卡尔曼滤波，对于LOS使用标准卡尔曼滤波(Biased Kalman filter can be used to eliminate the wireless location in NLOS error, the program joined the non-line-detection module, for use NLOS biased Kalman filter, using the standard Kalman filter for the LOS)
