Patent ID: 7466667

Claim:
A wireless receiver that receives a received signal from a wireless channel and detects from the received signal the presence of a packet, the wireless receiver comprising: a packet detector having an adaptive packet detection process; logic to process the received signal when the packet detector indicates presence of a packet; a false detection determiner for determining whether the signal indeed represents a packet; and logic for adjusting the adaptive packet detection process when a false detection metric is outside a target range wherein the adaptive packet detection process, based on the logic for adjusting the adaptive packet detection process and/or a false detection metric, adjusts a threshold for a given detection test accordingly and wherein the adjustment of the threshold is such that when a false detection rate is higher than a maximum desired false detection rate, the threshold for a given test is raised by a first incremental value, when the false detection rate is lower than a minimum desired false detection rate, the threshold for the given test is lowered by the same or a different incremental value, and when the false detection rate is between the minimum desired false detection rate and the maximum desired false detection rate, the threshold value is not modified.
