Abstract
A system and method for improving the accuracy in computing the location of a mobile subscriber device connected in a wireless network. The system and method employ a predictive filter, including a measurement weight algorithm to decrease standard deviation error, to correctly determine a location of a mobile subscriber device. The predictive filter requires lower levels of computation, which allows for real-time processing on low-speed central processing units commonly used in wireless networks.
