Adaptive angle of arrival estimation for multiuser wireless location systems
2004
Proceedings of the IEEE 5th Workshop on Signal Processing Advances in Wireless Communications, 2004.
Reliable positioning of CDMA cellular users in a mobile environment relies on accurate knowledge of the time-of-arrival (TOA) and angle-of-arrival (AOA) of the first arriving ray. An adaptive procedure is developed for AOA estimation under multipath and multiuser conditions. Simulations illustrate how the adaptive solution improves location accuracy.
