  • Method and apparatus to facilitate detection of an unauthorized communication system user
    Patent number: 8509735
    Abstract: A correlating receiver is used (102) at a code division multiple access base transceiver station to monitor what may comprise possible multi-path versions of a transmission from an authorized communication system user to provide monitoring results. These monitoring results are then used (103) to detect when one of the possible multi-path versions of the transmission was sourced by an unauthorized communication system user while at least another of the possible multi-path versions of the transmission was, in fact, sourced by an authorized communication system user. In a preferred approach the unauthorized communication system user is then identified (104) as being a clone.
