基于非圆信号波达方向估计的最大似然算法
Maximum Likelihood Algorithm for Direction-of-arrival Estimation of Noncircular Signals
摘要
Abstract
Most of the existing algorithms for DOA estimation of noncircular signals belong to the subspace eigenvalue decomposition algorithm, such as NC-MUSIC algorithm and NC-ESPRIT algorithm. Algorithms for DOA estimation of noncircular signals hased on subspace fitting havent been researched very much. According to the data mode for DOA estimation based on noncircular signals,a maximum likelihood algorithm for DOA estimation of noncircular signals i8 proposed in the paper. The comparison between the NC-ML algorithm and the comentional ML algorithm is presented based on the computer emulation. And the same comparison is presented between the NC-ML algorithm and the NC-MUSIC algorithm. The efficacy shows that the NC-ML algorithm improves the estimalion capacity. This algonthm can play an impmtant role in the situation which is having lots of users and requiring high estinWion precision.关键词
