Direction-of-Arrival Estimation of Mixed Coherent and Uncorrelated Signals
Saidur R. Pavel, Yimin D. Zhang
Abstract
This letter develops a new direction-of-arrival (DOA) estimation method for mixed coherent and uncorrelated signals through the reconstruction of a set of Toeplitz matrices. More specifically, Toeplitz matrices are formed by utilizing the rows and columns of the covariance matrix, and their average is used by subspace-based algorithms to effectively estimate the signal DOAs. Compared to existing methods, the proposed approach provides a high number of degrees of freedom and requires a low computation complexity.
