Method and apparatus for mobile application recognition based on physical layer traffic meta information

By using a physical layer traffic metadata-based identification method, IQ signals are acquired and processed to generate power spectra. User traffic is separated using adaptive threshold and density clustering, and classified using neural networks. This solves the identification failure problem caused by link layer encryption in mobile communication scenarios, and achieves efficient and accurate application identification.
