Abstract
The paper presented a comparison of some of the current techniques used for mobile location in a cellular system. It highlighted the problem of multipath fading in providing accurate estimations of time and angle of arrival and it compared the effect of location geometry on the time of arrival (TOA) and angle of arrival (AOA) in terms of their GDOP. It illustrated the impact of different AOA estimation techniques such as MUSIC and ESPRIT on the accuracy of AOA estimation. The errors of both TOA and AOA methods are obtained in multipath fading and it is concluded that, for the geometry stated, the AOA is more accurate than the TOA
