Direction-of-Arrival Estimation Method for Principal Singular Vectors Based on Multiple Toeplitz Matrices

Table 1

Implementation steps of the proposed algorithm.

---

(1) An equivalent is obtained through calculation of formulas (3), (5), (6), (7) and (8)
(2) The Toeplitz matrix containing DOA information is constructed by using formula (10)
(3) Formulas (14)–(16) were combined to obtain formula (18)
(4) Initialize by using in formula (21), and utilize the to construct via formula (18)
(5) The exact is obtained through several iterations of formulas (18) and (20)
(6) All DOA candidates were obtained by calculating formula (22)
(7) DOA values were obtained from all DOA candidates via formula (23)
