MATLAB中有专用的通信工具箱，里面提供了相当多的通信方面的函数，使用户能 轻松地进行通信方面的分析与处理，用户也可以自己编程解决问题(There are dedicated MATLAB toolbox of communication, which provides a considerable number of communications functions, allows users to easily communicate analysis and processing, the user can also be programmed to solve the problem themselves)

A fingerprint recognizing system is built with two principal components: the fingerprint admin istrator and the fingerprint recognizer. Fingerprints are identified by their special features such as ridge endings, ridge bifurcation, short ridges, and ridge enclosures, which are collectively called the minutiae.
