Duan Chen-dong · Modern Electronics Technique · 2012
A new DOA(direction-of-arrival) estimation method based on an algorithm for fast blind source separation(FBSS-DOA) is proposed in this paper.A group of correlation matrices possessing diagonal structure is 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 was then estimated and the estimation of DOA was realized.Compared with familiar algorithms,the algorithm has more generality and better estimation performance.The simulation results illustrate its efficiency.
