Abstract

Abstract:

A digital modulation recognition algorithm using intrinsic time-scale decomposition and the parameters separability for feature extraction and selection is proposed. Simulation results show that the average recognition rate is higher than 94％ using only three feature parameters when the SNR is above 5dB. This algorithm is not sensitive to the carrier frequency offset and symbol synchronization with low complexity and real-time realization, and it is suitable for the signal reconnaissance system and interference reconstruction concellation system.

Key words: modulation classification, intrinsic time-scale decomposition, feature selection
