摘要：
This paper addresses the signal-strength-of-arrival (SSOA) based localization problem with unknown transmit power, which is of vital importance for the rescue system in ruins scenarios. First, a semidefinite programming method is proposed to transform the nonconvex and nonlinear problem into a convex optimization problem, which presents an excellent performance even in the high interference situations. Besides, the accuracy degradation due to the estimation error of the transmit power is investigated. Simulation results confirm the effectiveness of the proposed methods.
