Recognition algorithm of telegraph signal based on Matlab

无线报务信号自动识别是无线报务自动接收的基础。借助Matlab软件强大的数据处理能力,可以比较方便地实现无线报务信号的识别,进而达到无线报务信号自动接收的目的。无线报务信号识别需解决无线报务信号频率分析与处理、信号频率二值化和规整、报文自适应识别等任务,其算法结果可以方便地封装为动态链接库供其它程序调用。该算法已成功应用于某型无线报务自动侦收装备,使用结果表明:该算法结构简洁、运算效率高、识别准确等优点,达到报文自动识别实用性要求。

The auto-recognition of telegraph is the base of telegraph signal auto-receive. With the help of Matlab, autorecognition of telegraph can be implemented conveniently, and moreover the aim of telegraph signal auto-receive is reached. The Recognition telegraph signal includes the following three tasks： firstly, the analysis and processing of the signal frequency; secondly, the numerical value of the frequency; finally, the adaptive recognition of telegraph. The result of the algorithm can be encapsulated into a DLL for the use of other application. This algorithm has been used in a device of auto-recognition of telegraph. The result means that the algorithm has the advantages of simple structure, high efficiency and exact recognition, and meets the need of auto-recognition well.
