Abstract
Methods and apparatuses for dynamically adjusting the sensitivity of a receiver for detecting air frames destined for the receiver may generally include determining a number of false frames previously detected by a wireless receiver in a period of time and adjusting a threshold to be compared with correlation output used to detect frames based on the determined number of false frames previously detected. In this manner, the sensitivity for a receiver in detecting frames may be increased or decreased based on the current environment in the wireless network. Additional embodiments and variations are also disclosed.
