Patent ID: 7480234

Claim:
A method comprising: wirelessly receiving a signal; detecting a start of packet (SOP) from the received signal using at least one SOP detection criterion for a packet that conforms to a wireless networking standard; determining a plurality of metrics from the received signal; and in the case an SOP is detected, using at least two of the plurality of metrics to determine an initial timing for a received packet, wherein a packet according the wireless networking standard includes a preamble, and wherein detecting the SOP includes using at least one of the set of SOP methods that comprises: detecting that a threshold was exceeded by a measure of the average received signal power; detecting that a threshold was exceeded by a measure of the average power rise of the received signal; and detecting that a threshold was exceeded by a measure of the quality of the correlation of the input signal with a known part of the preamble, and detecting a rise in a weighted sum of the measure of the average received signal power and the measure of the correlation of the input signal with the known part of the preamble.
