Abstract: The present disclosure relates to the technical field of wireless communications, in particular, a digital predistortion (DPD) apparatus applicable to a 5G broadband multiple-input multiple-output (MIMO) system. The DPD apparatus includes a data processing module, a digital-to-analog conversion module, a signal output module, a signal feedback module, and an analog-to-digital conversion module; the signal feedback module is to ensure that at least two feedback paths are directed to a DPD feedback signal. The first feedback path is a main feedback loop, and the second feedback path is an auxiliary feedback loop. The present disclosure has the advantages of occupying a few of hardware resources, being capable of monitoring a DPD feedback loop signal in real time, and making a response in time.

Abstract: A method is capable of offline authenticating a passcode which is generated online by encoding time related information with a shared private key. The authentication process decodes the time related information from passcode with the same shared private key and compares the decoded time related information with the point of time of authenticating to determine whether the passcode is valid at the present time or not. The authentication is performing locally and independently without connection to other separated device, services, components or storage.
