Wireless localization has a great importance in variety of areas including commercial, service, and military positioning tracking systems. In harsh indoor environments, it is hard to localize an agent with high accuracy due non-line-of-sight (NLOS) radio blockage or insufficient information from anchors. Therefore, NLOS identification mitigation are highlighted as effective way improve the accuracy. this paper, we develop robust efficient algorithm enhance for (ultrawide bandwidth)...
