Performance Analysis and Evaluation of Hybrid Compensation Algorithm for Localization

Abstract In this paper, the hybrid compensation algorithm(A HB ) for localization using the Compensation Algorithm distance(CA d ) and the Algorithm of Equivalent Distance Rate(AEDR) in SDS-TWR(Symmetric Double-Sided Two-Way Ranging) is suggested and the performance of the proposed algorithm is analyzed by practical experimentations. From experimentations, it is confirmed that the errors are reduced in 28 coordinates of total 32 coordinates in the experimental region and the errors are reduced about above 70% in the assigned 3 type error level ranges by A HB . Also, it is analyzed that the average localization error is reduced from 2.67m to 1.19m as 55.4% in total 32 coordinates by A HB and the error compensation capability of A HB is very excellent as above 90%. From above results, we have seen that the error reduction ratio and error compensation capability of A HB is more excellent than each CA d or AEDR.
