基于频率偏差抵消的TDOA无线定位新方案
New Wireless Location Scheme Based on Frequency Deviation Elimination
摘要
Abstract
The location technology based on TDOA is widely paid attention today . TWR and SDS -TWR wireless ranging principle and algorithm is introduced first, and their ranging precision is analyzed simply. Wireless location scheme based on TDOA of OWR is introduced, using the same time interval between two data sending and receiving, and using SDS - TWR ranging distance deviation formula to calculate each frequency deviation of the two nodes, which is used to improve the location precision. The simulation results show that the method can significantly improve the precision of the wireless location system based on TDOA.关键词
