  • Patent number: 9848384
    Abstract: Apparatuses, methods, apparatuses, and systems for of selectively deactivating portions of a receiver based on dynamic measurements are disclosed. One embodiment of a method includes receiving, by the receiver, a wireless signal, identifying a packet within the wireless signal, determining whether the packet cannot be decoded with a reliability greater than a threshold, and powering down at least a portion of the receiver after determining that the packet cannot be decoded with the reliability greater than the threshold.
    Type: Grant
    Filed: February 11, 2016
    Date of Patent: December 19, 2017

  • Patent number: 9806871
    Abstract: Apparatuses, methods, apparatuses, and systems for selective subcarrier processing are disclosed. One embodiment of a method includes determining whether a signal quality of a received multi-carrier signal is better than a predetermined signal quality, wherein the predetermined signal quality is selected to ensure that a probability of error free decoding of the received signal is greater than a predetermined threshold, and after determining that the signal quality of the received multi-carrier signal is better than the predetermined signal quality, determining which of subcarriers of the multi-carrier signal to perform receive signal processing based on a relative signal quality of each of the subcarriers.

  • Patent number: 9281885
    Abstract: Apparatuses, methods and systems for beamforming based on encoding are disclosed. One embodiment of a method includes generating a beamforming matrix, including obtaining a channel matrix of a multiple-input, multiple-output (MIMO) channel between multiple transmitter antennas and at least one receiver antenna, determining an initial beamforming matrix based on a singular value decomposition of the channel matrix, and generating, by a transceiver, a final beamforming matrix comprising reordering columns of the initial beamforming matrix for at least one sub-carrier of a multi-carrier signal, wherein the reordering of the columns is based on knowledge of encoding of a transmit signal.
