瑞利衰落信道仿真的matlab代码.很不错的(rayleigh fading channel simulation)

说明：  hurst 指数计算程序 提示：先导入（import）时间序列数据，再进行计算。(hurst Index hints: first import (import) time-series data, and then calculated.)

matlab, document how to use matlab

用于时间序列的预测，包含序列特征描述、平稳性检验、序列周期判断、季节因子提取、指数平滑预测、及ARIMA预测(Sequence features for time series prediction, including the description of the stationary test, to determine the sequence cycle, seasonal factor extraction, exponential smoothing, and ARIMA forecasting)

读入语音信号，加入噪声后将其滤除再还原声音(Adding a pulse noise to an existed speech then filt it with a specified FIR filter.)

使用matlab语言实现现代信号处理_谱估计_周期图法(Modern Signal Processing PSD Period Graph Method.)

利用幂法和反幂法求解按模最小特征值，按模最大特征值。与MATLAB中eig功能相似 (get the character value of a matrix, similiar with the function eig in matlab)

谐波信号提取程序，可以用于信号谐波分量的分离(The harmonic signal extraction procedures, can be used for separation of signal harmonic component)

MVDR beamformer with interference

修正 Gram-Schmidt 正交 ，从别处找到的。(Gram-Schmidt orthogonal correction)
