An experimental performance evaluation of a novel radio-transmitter identification system under diverse environmental conditions Une ´ evaluation exp´ erimentale de la performance d'un nouveau syst` eme d'identification de transmetteur radio sous diverses conditions environnementales

摘要: ¨In this paper, the effects of environmental conditions on a radio-transmitter identification system are investigated. Transmissions from commercial VHF FM transmitters operating under varying analyzed using an experimental setup. It is observed that change in such as battery voltage or ambient temperature causes feature vectors to spread over space, resulting classification performance degradation. experimentally shown degradation changing can be compensated for by training with data collected range battery-voltage and levels. The signal-to-noise ratio versus probability correct also determined systems noisy channels order obtain confidence measure decision made. Th et ransient features extracted technique based amplitude sa nd phase changes received signals. This well suite dt o turn-on transient signals, classificatio nw ith these features, shown, outperforms current techniques.
