摘要: Authenticating wireless devices based on features of their transmitted waveform has become a topic considerable interest. Recent work in this arena shown that examination modulated can lead to highly precise identification 802.11 devices. This paper experimentally demonstrates improved accuracy and reduced sensitivity parameters when such techniques are applied the multiple transmitters within multiple-input multiple-output It further studies an information theoretic technique for determining which radiometric most effective discriminating analyzes performance as function number used. Finally, because some sensitive environmental conditions and, therefore, drift with time, analysis explores impact feature both prioritization performance.
