Abstract: In accordance with a first aspect of the present disclosure, a localization device is provided, comprising: an ultra-wideband, UWB, communication unit configured to transmit a localization signal to an external device and to receive a response signal from the external device; an angle of arrival measurement unit configured to measure an angle at which the response signal is received; an orientation sensor configured to sense an orientation of the localization device; and a processing unit configured to determine if an angle at which the localization signal is received by the external device, an orientation of the external device, said orientation of the localization device, and said angle at which the response signal is received meet a predefined relationship. In accordance with a second aspect of the present disclosure, a corresponding method of operating a localization device is conceived.

Abstract: Embodiments of methods and systems for gain control in a communications device are described. In an embodiment, a method for gain control in a communications device involves detecting a change in an amplification gain that is applied to an analog signal in the communications device and compensating for the change in the amplification gain by manipulating an amplitude of a digital signal that is converted from the analog signal. Other embodiments are also described.

Abstract: A system includes a signal processing unit including an antenna configured to receive a radio frequency signal as a received radio frequency signal, and a baseband amplifier coupled to the antenna. The system includes a processor configured to cause the communication unit to stop generating a radio frequency polling signal, set an amplification gain of the baseband amplifier to a first gain value, periodically record, at a sample rate, an indication of a magnitude of the amplified radio frequency signal to generate a plurality of sample values, at a predetermined time interval after the communication unit stopped generating the radio frequency polling signal, set the amplification gain of the baseband amplifier to a second gain value, and transmit the plurality of sample values to a classifier module to determine whether the radio frequency signal is received from a near-field communication-enabled device.

Abstract: Methods for operating a communications device that communicates via inductive coupling, methods for operating an NFC device, and a communications device that communicates via inductive coupling are disclosed. In an embodiment, a method involves at the communications device, shifting a first transmission phase to obtain an updated transmission phase in response to information from a corresponding reader device, which indicates that active load modulation (ALM) communications between the communications device and the corresponding reader device under the first transmission phase fail, at the communications device, conducting subsequent ALM communications with the corresponding reader device under the updated transmission phase, in response to that the subsequent ALM communications under the updated transmission phase are successfully conducted between the communications device and the corresponding reader device, obtaining a new training data point based on the updated transmission phase, and training the communications device in response to the new training data point.
