仿真QPSK，包含源程序，调制，解调过程也有，仅供参考。(simulationQPSK)

说明：  在原始信号加入白噪声，通过卡尔曼滤波去除噪声，恢复原始信号。(In the original signal to join the white noise through the kalman filter remove the noise, restore the original signal. )

用于分类的主判别变量算法(principal discriminant variate algorithm) ( principal discriminant variate algorithm for two classes, x1 and x2. x1 is the training samples in the 1st class with each column being the spectrum characterizing the corresponding sample. x2 is the training samples in the 2nd class with each column being the spectrum characterizing the corresponding sample. lamda is the penalty weight defining the balance between FLDA and PCA. dvnum is the number of principal discriminant variates to be computed. A defaul value for dvnum is 2. dv is the principal discriminant variates. scores is the matrix with each row being the scores of the samples on the corresponding principal discriminant variate. xmean is the mean spectra of the sample, which was used for mean-centering the data in training and prediction. )
