Patent ID: 11868511
Assignee: BEIJING BOE TECHNOLOGY DEVELOPMENT CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 7:
8. A method for generating a digital fingerprint, comprising:
acquiring a control word;
outputting a first pulse signal in response to the control word:
outputting a second pulse signal in response to the control word, wherein the first pulse signal and the second pulse signal are generated by circuits with a same structure, each of the first pulse signal and the second pulse signal comprises a first frequency signal and a second frequency signal, and probabilities of occurrence of the first frequency signal and the second frequency signal are controlled by the control word; and
outputting a digital fingerprint, based on the first pulse signal and the second pulse signal, according to a predetermined first rule;
wherein outputting the first pulse signal in response to the control word comprises:
generating the first pulse signal in response to reference pulse signals with uniformly spaced phases, and the control word; wherein
the control word comprises a first coefficient and a second coefficient; and
the first pulse signal comprises the first frequency signal generated based on the reference pulse signals and the first coefficient, and the second frequency signal generated based on the reference pulse signals and the first coefficient, wherein a ratio of the first frequency signal to the second frequency signal in the first pulse signal is controlled by the second coefficient.
