Embodiment 1
[0079] Embodiment 1: Numerical simulation experiment of the above-mentioned system model and identification method.
[0080] The numerical simulation experiment is based on a communication individual and the corresponding wireless channel, and the separation experiment of the transmitter PA nonlinear model coefficient and the wireless channel unit impulse response is carried out. Then, the basic k-NN classifier is used to classify two communication individuals and corresponding wireless channels based on the feature vectors formed by the separation parameters.
[0081] Such as Figure 4 Shown is the schematic diagram of the simulation experiment scene. Transmitter-1 and Transmitter-2 respectively represent two different communication individuals, and Channel-1 and Channel-2 are wireless channels between Transmitter-1, Transmitter-2 and the receiver, respectively. Transmitter-1 and Channel-1 constitute a "transmitter and wireless channel pair", represented by Transmitter-1 / Ch...

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...
