N2 - This paper introduces an improved de-noising SOBI (Second Order Blind Identification) separation method, which is used to separate mixed components of different composite materials damage acoustic emission simulated signals. The contrastive analysis and numerical simulations of a variety of blind source separation algorithms are investigated, which suggests that traditional SOBI performance degrades when noise is present. By introducing noise-elimination algorithms, SOBI is improved and optimized. The improvement of separation effect of the de-noising SOBI algorithm is proved by numerical simulation experiments. Finally, based on the online structural damage simulation and monitoring test-bed, the feasibility of the proposed method is validated.
