A UWB Positioning Scheme Based on BP Neural Network in NLOS Environment

Ultra-wideband can provide precision location due to the high time resolution properties. When the direct LOS between two nodes blocked by the obstacles in indoor positioning environments. The NLOS in TOA estimation may lead to immense error in positioning. A new method using neural network was employed to mitigate the NLOS effect in UWB positioning scheme. Simulations show it works well.
