Abstract

In one embodiment, a method includes receiving a radio frequency (RF) signal; synchronizing the received RF signal with a preamble to determine a time base; determining a first energy value of the received RF signal by averaging received signal strength indication (RSSI) values of the received RF signal over a first period of time; determining a second energy value of the received RF signal over a second period of time; determining a difference value between the first energy value and the second energy value; comparing the difference value with a predetermined energy threshold value; determining a quality value of the received RF signal; comparing the quality value of the received RF signal with a predetermined quality threshold value; and, if the difference value exceeds the predetermined energy threshold value or the quality value is below the predetermined quality threshold value, then erasing the time base.
