Abstract
A DVB-T(Digital Video Broadcast-Terrestrial) signal location scheme is proposed combining TDOA location model and Fang algorithm in cellular wireless location technology.This positioning scheme directly uses the symbolic synchronization algorithm to measure the TOA/TDOA value, so there is no need to use other TOA estimation algorithm or TDOA cross-correlation estimation algorithm. Meanwhile, the synchronization algorithm better overcomes the adverse effects of multipath and NLOS. Therefore, NLOS error suppression algorithm and TOA/TDOA smoothing and reconstruction algorithm are no longer needed.Simulation results show that the positioning algorithm is affected by the ranging accuracy and cell radius, with higher the location accuracy.
