  • Method and system for determining mobile unit location by aggregation of tagged signals from a distributed antenna system
    Publication number: 20050153712
    Abstract: A method for determining the location of a mobile unit tags uplink signals received at separate antennas with corresponding antenna tags. All of the uplink signals are combined into a single combined signal, which may be transmitted to a base station. One or more signal parts are selected from the combined signal, and these selected parts are decoded to determine their corresponding antenna tags. A location algorithm is applied to the decoded signal parts to determine a location of the mobile unit.
