摘要 提出一种基于快速盲源分离算法实现波达方向(DOA)估计的方法。构造了具有对角化结构的相关矩阵组,引入解盲源分离问题的联合对角化代价函数,采用一种快速的复数域乘性迭代算法求解代价函数,得到混迭矩阵逆的估计,进而实现DOA估计。与同类算法相比,该算法具有更广的适用性和更精确的DOA估计性能。仿真实验结果验证了算法的快速收敛性和优越的估计性能。 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.
