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.
Claims29
A receiver, comprising:
- a receive chain operative to receive a multi-carrier signal;
- a controller, the controller operative to:
- determine whether a signal quality of the 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;
- determine which of subcarriers of the multi-carrier signal not to perform receive signal processing based on a relative signal quality of each of the subcarriers after determining that the signal quality of the received multi-carrier signal is better than the predetermined signal quality.
A method, comprising:
- 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;
