Abstract
A system for terminating a receive correlation window of a receiving wireless device includes a radio frequency receiver configured to open a receive correlation window having a predetermined duration and an energy measurement circuit configured to measure a radio frequency energy level ambient to the wireless receiver. A comparator is included that is configured to determine, based on the measured radio frequency energy level, whether or not a signal is being transmitted from a nearby wireless device. The receiver is further configured to close the receive correlation window before the predetermined duration is reached in response to a determination by the comparator that no signal is being transmitted by a nearby device. If a signal is being transmitted, then the receive correlation window is allowed to proceed uninterrupted.
