Abstract: A radio receiver includes a channel estimator processing circuit including: a feature extractor configured to extract one or more features from a received signal, the features including a channel correlation estimated based on a reference signal in a current slot, the estimated channel correlation indicating a rate of change of a wireless channel over time; and a Doppler spread estimator configured to estimate a Doppler spread of the wireless channel by supplying the features to one or more Doppler shift predictors trained on training data across a training signal-to-noise ratio (SNR) range and across a training Doppler shift range, each Doppler shift predictor being trained on a portion of the training data corresponding to a different portion of the training data.

Abstract: A method and system are herein disclosed. The method includes receiving sounding reference signals (SRS) at a massive multiple-input multiple-output (MIMO) base station (BS) from a user equipment (UE), determining, at the BS, beamformers for known channels of the SRS, determining, at the BS, beamformers for unknown channels of the SRS based on the determined beamformers for the known channels, and selecting a modulation and coding scheme (MCS) based on the determined beamformers.

Abstract: An electronic device and a method for managing an electronic key thereof are provided. The electronic device includes a wireless communication circuit, a hardware-based security element comprising circuitry configured to provide a timestamp, a processor operatively coupled with the communication circuit and the security element, and a memory operatively coupled with the processor. The memory stores instructions that when executed by the processor, control the electronic device to: launch an application related with an electronic key of a door lock, receive an input for using the electronic key to open the door lock through the application, determine the validity of credential information related with the input, based at least in part on the timestamp, and open the door lock based on the validity of the credential information.

Abstract: A method and apparatus are provided. The method includes receiving a signal from a transceiver, demapping a bit pattern encoded within the signal, detecting a preamble based on the demapped bit pattern, and synchronizing the transceiver to a receiver using the preamble, wherein demapping the bit pattern is based on weighting coefficients.
