Abstract

Abstract: Aiming at the practical requirements of blind separation process of acoustic signals, a modeling method of acoustic signals separation simulation system based on SystemVue simulation platform is proposed according to specific mode of signal separation and acoustic sensor network layout in the practical work. It provides a novel signal separation algorithm based on signal single source detection which is the improvement of FastICA algorithm. It also can obtain the source acoustic signals without the information of signal source numbers. The SystemVue software is used to model the net of acoustic sensors, and the target simulation information is generated at the same time. In the simulation, the comparison between proposed signal separation algorithm and traditional algorithms is to prove the feasibility and superiority of the proposed algorithm. It is approved that the modeling scheme is correct and realizable by the simulation experiment.
