Patent ID: 8385390

Claim:
A method of extracting data from data packets transmitted over a wireless network, the method comprising: receiving a data packet, the data packet having a preamble portion and a payload portion, the preamble portion comprising i) a first cover code combined with a first known spreading sequence and ii) a second cover code combined with a second known spreading sequence; cross correlating the preamble portion with the first known spreading sequence to generate a first timing signal; cross correlating the preamble portion with the second known spreading sequence to generate a frame timing signal; detecting an impulse in the first timing signal; setting a first timing parameter based upon the detected impulse in the first timing signal; detecting an impulse in the frame timing signal; setting a frame timing parameter based upon the detected impulse in the frame timing signal; extracting data from the received payload portion according to the set first timing parameter and the set frame timing parameter; and extracting one or more physical layer parameters from at least one of the first cover code and the second cover code.
