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".

说明：  在本系统中，信息序列在先经过FSK调制，经过截止频率为25kHz的低通滤波器后（把信号频率限制在25kHz），再进入混频器搬移到更高的频率发送出去，在接收端，用与发送端同步的跳频信号对其进行变频（跳频的解跳处理在此进行），取下边频，然后进行FSK的解调(In this system, the message sequence prior through FSK modulation, through the cut-off frequency of 25kHz after low-pass filter (to limit the frequency 25kHz), and then move into the mixer to a higher frequency to send out, at the receiving end used with frequency hopping synchronization signal transmitter carried on their conversion (FH' s solution to deal with this for jumping), take down side frequencies, then the demodulation of FSK)
