Physical layer parameter separation and individual identification method for single carrier communication system

Abstract

The present invention provides a physical layer parameter separation and individual identification method for a single carrier communication system. The method comprises the following steps: collecting a signal; constructing a nonlinear training sequence matrix; obtaining estimations of a nonlinear transmitter model coefficient and a Kronecker product of wireless channel unit pulse response based on the sending signal and the nonlinear training sequence matrix by a preset estimation algorithm; separating the two estimation parameters of the nonlinear transmitter model coefficient and the wireless channel unit pulse response by the a preset algorithm; combining the estimations of the nonlinear transmitter model coefficient and the wireless channel unit pulse response into a feature vector of the transmitter and a wireless channel pair; and training, classifying or identifying a communication source individual based on a sample of the feature vector. The physical layer parameter separation and individual identification method is applied to the joint estimation and separation of the nonlinear transmitter model coefficient and the wireless channel unit pulse response, and can be applied to parameter separation and individual identification based on communication transmitter hardware and single carrier radio equipment of the position and other fields.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a physical layer parameter separation and individual identification method of a single-carrier communication system. Background technique [0002] Due to its advantages such as mobility, single-carrier wireless communication technology is widely used in physical layer data transmission of radio equipment. In order to ensure the information security of communication between radio devices, the identity authentication of the communication party should be carried out first, and then the encrypted transmission of communication data should be carried out. [0003] Identity authentication is generally based on passwords and authentication protocols. The communication initiator generally confirms whether the other party is a legitimate communication party through a challenge-response authentication protocol based on encryption and decryption. However, in addition to bein...
