介绍TDOA(Time Difference of Arrival)技术的数学模型,以及TDOA技术在GSM(Global System for Mobile Communication)和CDMA(Code Division Multiple Access)网络的实际应用。最后通过仿真分析,对GSM和CDMA网络进行了性能比较,深入分析了两种网络的特点,对于在实际应用中如何选择定位网络有很好的指导作用,具有很高的实际应用价值。
TDOA( Time Difference of Arrival)technology mathematics model was produced and it was applied to actual GSM( Global System for Mobile Communication)and CDMA( Code Division Muhiple Access)network. Finally compared GSM network performance with CDMA network by simulation analysis and analyzed two networks characteristic. It had a good guidance function to how to select location network in practice and high practice application value.
