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.)

coherencee mvdr
—The minimum variance distortionless response
(MVDR) approach is very popular in array processing. It is also
employed in spectral estimation where the Fourier matrix is used
in the optimization process. First, we give a general form of the
MVDR where any unitary matrix can be used to estimate the
spectrum. Second and most importantly, we show how the MVDR
method can be used to estimate the magnitude squared coherence
function, which is very useful in so many applications but so few
methods exist to estimate it. Simulations show that our algorithm
givesmuchmore reliable results than the one based on the popular
Welch’s method.

multipath_test
该程序是自己编写的,是基于matlab的多径信道的建立。该多径信道是基于电力线信道特性而构建的,其中的衰落系数是通过阅读大量文献而得到的。该程序能够顺利运行,并画出了信道的各个参数图。(The program is written by myself,which is to build a multi-path channel matlab based. The multi-path channel is based on the characteristics of the power line channel constructed, which is fading coefficients obtained by reading a lot of literature. The program can run smoothly, and draw a diagram of each parameter channel.)
