频谱估计Automatic Spectral Analysis-Matlab code(Accurate estimates of the autocorrelation or power spectrum can be obtained with a parametric model (AR, MA or ARMA). With automatic inference, not only the model parameters but also the model structure are determined from the data. It is assumed that the ARMASA toolbox is present.)

频谱的比值校正，汉宁、矩形、海明窗的具体算法，原理等，比较详细的分析程序(spectrum correction)

Security algorithms on WSN are devided on two kinds: symetric and asymetric. AES is one of the rebust os symetric methods. AES is simulated with matalb. Very intersting and very useful.
