SIGNAL IDENTIFICATION METHOD AND SYSTEM BASED ON RADIO SIGNAL SPECTRUM FEATURE TEMPLATE

摘要

The present invention provides a signal identification method based on a radio signal spectrum feature template. The method comprises: constructing a signal template library by extracting spectrum features of a plurality of radio signals; preprocessing a signal to be identified according to an expression form of signal templates in the signal template library; comparing and matching the preprocessed signal to be identified with the signal spectrum template library to obtain a type and a spectrum feature parameter of the signal to be identified. The present invention also provides a signal identification system based on a radio signal spectrum feature template, comprising a template construction unit, a preprocessing unit, and a matching unit. In the present invention, the spectrum template can represent various types of signals, the signal identification algorithm is further simplified while ensuring the accuracy of signal identification.
