摘要
In this paper, a new position location (PL) estimation technique for CDMA wireless communications system is proposed. The proposed technique provides faster solution to the hyperbolic model and does not suffer from the convergence problem. The performance of the proposed PL technique has been tested by considering different system parameters, such as channel noise and variable position of the user. Test results show that the proposed PL technique can successfully determine the position of a wireless user under various challenging scenarios. Copyright (C) 2011 John Wiley & Sons, Ltd.
