An Overview of Individual Feature Extraction Techniques
Mao Xing-peng · Telecommunication Engineering · 2011
Feature extraction is the key to emitter individual identification technology,but also the primary issue that should be solved in practical applications.From both transient aspect and steady-state aspect of the received signal,the exiting techniques of transmitter individual feature extraction are reviewed,the application scope and key issues of different extraction techniques are summarized.Also,in combination with requirements of the individual identification receiver,both the measuring conditions and limitations of the extracted feature parameters in engineering application are analysed and compared.Finally,the problems of existing extraction techniques are presented,as well as certain future research directions of individual identification technology.
