  Abstract

This paper shows the performance improvement of IPDL(ldle Period Down Link) by using PE(Positioning Element) in the presence of the hearability and DOP(Dilution Of Precision) problems which are designated as major obstacles in wireless position locations. To enhance the location performance, this paper introduces the high resolution technique for estimating a series of channel parameters especially the relative time delay of first arrival among multipath delays. For a systematic analysis of the proposed location method, its performances are exploited by obeying the CODIT channel model specially under the urban environment. Throughout exhaustive simulation results, this paper verifies the superiority of our proposed scheme in the sense of the resolution of TDOA(Time Difference of Arrival) parameters and the accuracy of overall location performance in average sense.
