用PSO优化LSSVM的参数，得到最优参数，使得分类更加准确。(Using the PSO the LSSVM the parameter, the optimal parameters, more accurate classification. )

说明：  生成C/A码的小程序，还可以计算自相关性(Generated C/A code small programs can also calculate the autocorrelation)

It generates the hamming code table

说明：  matlab m语言编写的拼图游戏，对于学习matlab很有帮助-matlab m jigsaw puzzle languages, matlab helpful for learning(matlab m language of the jigsaw puzzle, matlab helpful for learning-matlab m jigsaw puzzle languages, matlab helpful for learning)

功率谱估计（周期图法、welch法、pmusic法等）(PSD estimation)

几篇关于神经网络泛化的论文.几篇关于神经网络泛化的论文(several neural network generalization of the papers. Several of the generalization of the neural network papers)

非线性系统分析与仿真，非线性系统分析与仿真(Nonlinear system analysis and simulation, non-linear system analysis and simulation)

对函数进行采样，经过FFT变换后，画出频谱图，估计出频率。(Sampling of the function, after the FFT transform, the spectrum drawn to estimate the frequency.)

基于广义逆的最小二乘曲线拟合，采用满秩分解，用其中一个就可以了，单个太小，不让上传，所以复制三份(curve fitting by using generalized inverse matrix )

This is PAPR for CPM-SC-FDMA
