建立自回归滑动平均时间序列模型ARIMA,用来预测未来数据值(time series model-ARIMA to predict the future value )

说明：  Kriging插值算法的matlab工具包程序(Kriging matlab toolkit program)

freqz对一个采样频率为45.5MHz的信号进行14倍的抽取滤波，同时进行补偿滤波器的设计，并给出CIC滤波器、补偿滤波器和级联后的频谱图 ( for the droop in the passband for the CIC decimator.Design a minimum-order CIC compensator that compensates... . )

This routine performes trellis quanization of input sequence and provides output which should be further arithmetically coded. The program can be used for research ot teaching purposes to study performance of vector quantization, in particlular code-based trellis (multidimensional lattice) quantization.
