摘要
介绍如何从汽车接收到的数字电视信号中提取发射台的发射时间,得到接收机与发射台之间的伪距来进行定位,进行了误差分析,并与GPS定位做了比较。研究是基于欧洲数字电视传输标准DVB-T和清华大学的标准DMB-T。
Mainly investigates how to extract the transmitting time from car, s received DTV signal, then get the pseudo- distance between the receiver and the transmitter for position and its error analysis related, and the results with GPS position. Here .just based on DVB - T and DMB - T only.
