A New Statistical Time of Arrival Ranging Algorithm

چکیده
The accuracy of 60 GHz millimeter wave based indoor localization is mainly determined by the accuracy of the measurements employed. These measurements can be affected by the propagation environment, such as multipath fading due to a Non Line of Sight (NLOS) channel. To improve the localization accuracy, a new ranging algorithm for 60 GHz wireless systems is proposed based on Time of Arrival (TOA) measurements. This algorithm is compared with previously developed approaches such as the Mean Value Algorithm (MVA) and the High Probability Algorithm (HPA) using the IEEE 802.15.3c indoor channel model. Performance results are presented which show that the proposed algorithm can provide improved accuracy, particularly in poor channel conditions.
