A New Technique Using Signal Correlation of One Node B to Estimate Mobile Location

In Universal Intelligent Positioning System (UIPS) project, Location Determining Techniques were developed to estimate mobile user's location (position) in 2G, 3G and beyond networks. Timing techniques were developed to improve accuracy of estimating mobile user's location when measurements (such as time differences of arrival) are available from 2 and more than 2 Node B (base station). In this extension of study, a technique called Signal Correlation Method (SCM), based on Artificial Neural Network is introduced when measurements are only available from one serving Node B. Received signals collected during drive test (survey) are stored in UIPS servers.
