摘要:In this paper, we proposed a high precision location estimation algorithm using an intelligent coordination scheme in 2.45GHz RTLS and analyzed an average estimation error distance at 2D coordinates searching-area (300m¡Á300m and 250m¡Á250m). An average error distance was reduced as the number of available reader and received sub-blink increased. Proposed location estimation algorithm satisfied the RTLS specification requirements, 3m radius accuracy when the number of available reader is greater than 3 and the received sub-blink number exceeds 2 times in 250m¡Á250m. Also, an average error distance was saturated within 0.5m~2.5m in case of 250m¡Á250m when the number of available reader is greater than 4 regardless of the number of sub-blink. Also we confirmed that the 3m radius accuracy is 78 percent, and the 2.348m radius accuracy is 72 percent in 300m¡Á300m searching-area when the number of available reader and received sub-blink was 8 and 4 times, respectively. In that case, we confirmed that 3m radius accuracy is 99 percent, and the 2.348m radius accuracy is 97 percent in 250m¡Á250m searching-area
