Abstract
An apparatus for and a method of wirelessly receiving a signal, and detecting a start of packet (SOP) from the received signal using at least one SOP detection criterion. In the case an SOP is detected, determining a plurality of metrics from the received signal, and using at least two of the plurality of metrics to determine an initial timing for a received packet. Different versions combine the metrics in different ways to determine the initial timing. The apparatus includes a processing circuit coupled to a radio receiver to determine a plurality of metrics from a wirelessly received signal, and an initial time determining circuit coupled to the SOP detector and the processing circuit. In the case an SOP is detected, the initial time determining circuit uses at least two of the plurality of metrics to determine an initial timing for a received packet.
