指数平滑法是对时间序列进行预测常用的方法之一,其理论基础是趋势外延,即未来一定时期内事物在数量上的演变特征不脱离过去的发展趋势,预测值是以前所有观测值的加权和,且对不同的数据给予不同的权数,越近期数据给予越大的权数,越远期的数据给予越小的权数。(Exponential smoothing method is commonly used to predict the time series one of the ways, the theoretical basis of the trend of the extension, that is, a certain period of time what the next evolution in the number of characteristics are not out of the development trend of the past to predict the value of all previous observations is the weighted and, on different data and different weights given to more recent data to give greater weights, the more long-term data to give the smaller weights.)

说明: 信号的时间宽度和频率带宽反映的是 、 围绕 和 的扩展程度,信号的带宽( )完全由幅度、幅度的导数及相位的导数所决定。称T和B分别为信号 的时宽和带宽,TB称为时宽-带宽积,。此程序用于计算信号的时间宽度和频率带宽。(Signal time width and frequency bandwidth of reflected that and it spreads around the signal bandwidth () completely by the magnitude, amplitude and phase derivative of the derivative of the decision. Called T and B respectively when the signal width and bandwidth, TB is called when the wide- bandwidth product. This program is used to calculate the width of the signal time and frequency bandwidth.)

DSPfir
这是一个综合性的仿真程序。包括:用matlab生成一个FIR滤波器,得到滤波器系数及阶数;再用C语言产生一个混合频率的数字信号,之后将生成的数据样点送入到DSP主程序进行数字滤波,DSP主程序算法用的是循环缓冲区算法,这一部分在CCS上实现。(This is a comprehensive simulation program. Comprising: generating a matlab FIR filter, to obtain the filter coefficients and order then mixed to produce a C-frequency digital signal, and then the resulting data samples into the main program to the DSP for digital filtering, DSP main algorithm using a circular buffer algorithm, this part of the CCS to achieve.)
