Patent ID: 8159932

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: determining a logical function of at least two of a set of logical indicators, the set of logical indicators including: that a threshold was exceeded by the average received signal power; that a threshold was exceeded by the average power rise of the received signal; 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 that a threshold was exceeded by 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.
