These "personalized" communication systems also become important sources for intelligence gathering and monitoring of illegal activities. In this proposal, we propose to perform SEI (Specific Emitter Identification) based on the unintended modulation schemes that are inherent to the manufacturing of the communication transmitters. A set of SEI algorithms based on statistical approaches that utilize both frequency and I/Q domain data are described. The algorithms are applicable to various modulation types and are feasible for real time implementation. Based on the preliminary simulations, the proposed SEI algorithms indicate a high probability of success under noise, Rayleigh channel fading and multi-path interference conditions. The developed SEI algorithms will be tested based on both the simulated data and the Government provided data. Benefits: Successful completion of this program will advance the SEI technologies that are applicable to various types of modulation schemes used by communication systems of interest. One important benefit of the proposed SEI techniques is the applicability of the developed algorithms without requiring any a priori knowledge on the decoding schemes and modulation types. The proposed SEI techniques recognize the uniqueness of the emitter through the unintended modulation that is inherent to the manufacturing of the specific communication system transmitter. The proposed SEI techniques can be realized and configured for real time processing. Therefore, it allows effective data pre-processing (pre-screening) for the operators and intelligent analysts. Integrated with other intelligent gathering sensors, the proposed SEI techniques can enable a fully automated measurement system for monitoring and intelligence gathering applications. Return
