Wireless device classification through transmitter imperfections — Evaluation of performance degradation due to the chip heating

摘要: The wireless devices classification based on the transmitter imperfections is one of promising ways to provide additional security future communication networks. Although several aspects, both theoretical and practical, have been studied recently, there are no studies investigating degradation such authentication due environmental changes, as device temperature. We present initial results measurements RF-classification method Gaussian mixture model classifier under influence temperature variations. With use widely used USRP devices, we also try estimate which RF impairments sensitive changes.
