Analysis of HFDL Signal Recognition Method Based on Template Matching
This paper describes that because HFDL signals have a wide range of applications,filtering them out in signal detection can effectively reduce redundant information.To address the challenge of HFDL signal frequency estimation and detection in broadband,a method using standard spectral templates for correlation matching with the broadband signals under test has been adopted.This algorithm can achieve a rough estimation and identification of HFDL signal.Through comparative experiments,the effectiveness of the algorithm has been verified.
