Assignee: MICRON TECHNOLOGY, INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. A method, comprising:
receiving, from each antenna of a plurality of antennas, respective RF energies, each antenna coupled to a respective receiving unit of a plurality of receiving units;
for each respective receiving unit, autocorrelating a respective power of the respective RF energies to calculate a first statistic;
comparing, at a communication detector, the first statistic to a first threshold that indicates a presence or an absence of a wireless communications signal including encoded data;
providing a first signal indication based on a determination that the first statistic passes the first threshold, the first signal indication representative of the presence of the wireless communications signal including the encoded data;
based on obtaining the first signal indication, for each respective receiving unit, cross correlating symbols indicative of RF energy associated with a first antenna with at least other symbols indicative of RF energy associated with at least a second antenna to calculate a second statistic;
comparing, at a second communication detector, the second statistic to a second threshold that indicates the presence or the absence of the wireless communications signal including encoded data;
determining that the second statistic does not pass the second threshold;
providing a second signal indication representative of the absence of a wireless communications signal including encoded data; and
powering off a decoder responsive to receiving the second signal indicative of the absence of the wireless communication signal.
