Abstract: In a radio using a plurality of channels defined in a radio frequency (RF) spectrum, a rate of false packet detections may be calculated for each of the plurality of channels using a plurality of respective correlation thresholds. The rate of false packet detections for each channel may be compared to a range of acceptable rates of false packet detections. The same or different ranges of acceptable rates of false packet detections may be used for each channel or each channel plan. Different correlation thresholds may be adjusted based at least in part on the comparisons. For example, if a rate of false packet detections exceeds a range of acceptable rates of false packet detections, the correlation threshold may be raised, or the reverse. A packet may be detected on different channels based on different adjusted correlation thresholds.
