基于FPGA的射频指纹特征提取系统设计
System Design for RF Fingerprint Extraction Based on FPGA
摘要
Abstract
Signal distortion caused by the analog device will make the transmitted signal characterize the individual characteristics of the transmitter,which is called the radio frequency fingerprint.RF fingerprinting technology has been developed to identify the specific transmitter.At present,the implementation of RF fingerprint extraction and identification mostly depends on complex signal preprocessing and characteristic extraction algorithms with a huge amount of calculation.But in a reconnaissance system that requires rapid response and decision-making,due to limited computational resources,it is hard to meet real-time requirements.To address the requirements of radio frequency fingerprint identification systems in practical applications,a RF fingerprinting individual identification scheme is proposed for real-time requirement in non-synchronous situation and implanted based on FPGA,and the effective identification of hardware devices is verified with the help of linear classifiers.Under the condition of a signal-to-noise ratio of 0 dB,the identification rate of the characteristic combination is above 92%.关键词
