Abstract :
Multi-audio frequency signal have been applied in vary case. In this paper, a novel method for weak multi-audio frequency signal detection have been proposed. We aim at the multi-audio frequency signal detection in very strong noise circumstance based on the chaotic oscillator. At the end of paper, we exploit our approach to a typical multi-audio signal, TVM430 railway signal system, which have been widely used in railway. The experiment results demonstrate that the proposed method has preferable performance.
