A Design and Implementation of Compensation Algorithm for Radiodetermination Error using Determination Coordinator Value of Equivalent Distance Rate

In this paper, the compensation algorithm for radiodetermination error using a concept of determination coordinator value of equivalent distance rate (CADE) is proposed, and the performance of the proposed algorithm is analyzed. As a result of the experiments, CADE improves the performance of the algorithm accuracy about 37.5% and 69.8% each in the inside and outside of 4 beacon nodes. Furthermore, the CADE is 76.3% excellent enough to compensate 2m or more of the radiodetermination error. It also confirms that CADE can be adapted to the wide range by installing only 4 beacon nodes according to the excellence of compensation performance besides the ranges of 4 beacon nodes. From the results, it is strongly considered that the proposed algorithm CADE can be used to the performance enhancement of radiodetermination systems using SDS-TWR.
