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.

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.
