Table 1

Algorithm steps in this paper.

---

Step 1: construct the received data and from different matrix models and construct the Toeplitz matrix from equations (2) and (4)

Step 2: and are obtained from Toeplitz matrix and receiving matrix through formula (7)

Step 3: select all and to get and from formulas (8) and (9)

Step 4: is calculated from the formula

Step 5: perform feature decomposition on to obtain signal subspace

Step 6: get the corresponding and from , get the corresponding , and then perform feature decomposition

Step 7: match by equation (13) to obtain two-dimensional DOA estimation of P signals
