DS CDMA simulation matlab source code

可用于教学和学习使用，运行后可得到简图，使用语言为matlab(Can be used for teaching and learning to use, the operation can be obtained after diagram, using language for matlab)

非线性时间序列分析，相空间重构的参数选择,包括时间序列延迟计算和嵌入维数计算 (Nonlinear time series analysis, parameter selection phase space reconstruction, including time-series delay calculation and embedding dimension calculation)

从图片中提取四种不同纹理特征，包括gabor、灰度共生矩阵、灰度直方图、灰度梯度共生矩阵纹理特征。(Four different texture features extracted the image, including gabor, GLCM, histogram, GGCM texture.)

说明：  This program do bitplane slicing to embed watermark binary image in the least significant plane.Watermark is recovered even in presence of noise

DS-spread spectrum系统中,噪声为加性高斯白噪声,传统单用户检测,线性解相关多用户检测和最小均方误差多用户检测的性能比较(DS-spread spectrum system, the noise is additive white Gaussian noise, the traditional single-user detection, the linear decorrelating multiuser detection and MMSE Multiuser Detection Performance Comparison)

用MATLAB画南海地形图，但是前提要在SAT path里插入m_map文件(Nanhai topographic maps drawn using MATLAB, but only if you want to insert a file in the SAT path in m_map)

说明：  采用AR模型，估计功率谱密度，包含实测数据(The AR model is adopted to estimate the power spectral density, including the measured data)

自己编写的BFSK调制与解调，内含matlab-figure-file、matlab-M-file和得出的jpg格式图形！(I have written BFSK modulation and demodulation, containing matlab-figure-file, matlab-M-file and come to the jpg format graphics!)

说明：  用粒子群算法选择支持向量机的参数（来自于互联网，在此感谢原创）(With the particle swarm algorithm to select the parameters of support vector machines (from the Internet, would like to thank the original))
