在数字通信系统中，滤波器是其中重要部件之一， 滤波器特性的选择直接影响数字信号的恢复。在数字信号接收中， 滤波器的作用有两个方面，第一是使滤波器输出有用信号成分尽可能强；第二是抑制信号带外噪声，使滤波器输出噪声成分尽可能小，减小噪声对信号判决的影响。 (In digital communication system, the filter is one of the important components of the filter characteristics of the choice of a direct impact on digital signal recovery. In the digital signal receiver, the filter s role is twofold, first is to filter the output useful signal components strong as possible the second is the signal-band noise suppression, so that filter output noise components as small as possible, reducing the noise on the signal the impact of decision.)

BIRCH (balanced iterative reducing and clustering using hierarchies) is an unsupervised data mining algorithm used to perform hierarchical clustering over particularly large data-sets. An advantage of Birch is its ability to incrementally and dynamically cluster incoming, multi-dimensional metric data points in an attempt to produce the best quality clustering for a given set of resources (memory and time constraints). In most cases, Birch only requires a single scan of the database. In addition, Birch is recognized[1] as the, "first clustering algorithm proposed in the database area to handle noise (data points that are not part of the underlying pattern) effectively".
