A Direction-of-Arrival estimation method via Joint Diagonalization

A new Direction-of-Arrival (DOA) estimation method based on a Joint Diagonalization tool for Fast Blind Source Separation (FBSS-DOA) is proposed in this paper. A group of correlation matrices possessing diagonal structure are generated. A cost function of joint diagonalization for blind source separation is introduced. For solving this cost function, a fast multiplied iterative algorithm in complex-valued domain is utilized. The demixing matrix is then estimated and the estimation of DOA can be realized. Compared with existing algorithms, the algorithm has better generality and estimation performance. Simulations results illustrate its efficiency.
