Abstract
A method for exiting receiver processing in a FLO-EV receiver comprises receiving a communication signal comprising at least one received symbol, deriving a channel performance metric based on the received symbol, determining whether the metric exceeds a threshold, and when the metric exceeds the threshold, providing a logic signal to signal receiver processing cessation.
Claims19
A system for reducing power consumption in a FLO-EV receiver, comprising:
- a receiver configured to receive a communication signal comprising at least one received symbol;
- at least one channel performance indicator corresponding to the received symbol;
- a channel parameter estimate element configured to provide a channel energy profile for the received symbol;
- an interference variance element configured to receive the at least one channel performance indicator and provide an interference variance estimate for the received symbol;
- a mutual information calculation element configured to receive the interference variance estimate and the channel estimate, the mutual information calculation element configured to develop a metric for the received symbol;
- and
- a processor element configured to receive the metric and provide a logic signal to signal receiver processing cessation when the metric exceeds a threshold.
