Direct Position Determination with Single Sensor Based on Signal Periodicity

Table 1

Implementation of the proposed method.

---

(1) Choose a small constant and set , .

(2) Stack the received data vector and then compute related covariance matrices and subspace.

(3) Substitute , into (18) to estimate via grid search.

(4) Insert into (24) and (28) for estimating , , , respectively.

(5) If is smaller than e, regard as the position estimation. Otherwise, set , and return to step 3.
