Abstract

This paper presents a method for blind separation and DOA estimation of narrow-band independent signals based on eigenvalue decomposition. It can effectively improve the blind separation performance of array mixed signals under the condition of low signal-to-noise ratio. At the same time, the DOA of the separated signal is estimated. It is of great significance to improve the adaptability of array system in complex electromagnetic signal environment.
