Patent ID: 7965798

Claim:
An apparatus for robust packet detection in a packet-based wireless system, the apparatus comprising: a matched filter that is to produce at least one match indication indicative of a match between at least one signal received in at least one band and a reference signal, the at least one signal includes a first signal and a second signal, and the at least one band includes a first band and a second band; a multipath combiner that is to produce at least one multipath combined signal based upon the at least one match indication; wherein the at least one match indication includes a first match indication based on the first signal received in the first band and a second signal indication based on the second signal received in the second band, the least one multipath combined signal includes a first multipath combined signal and a second multipath combined signal, the first multipath combined based upon the first match indication, the second multipath combined signal based upon the second match indication; memory that is to store the first multipath combined signal; a per sample averaging unit that is to produce an average multipath combined signal based upon a per sample average of the first multipath combined signal and the second multipath combined signal; and a peak detector that is to identify a first peak in the average multipath combined signal to determine whether a packet reception is occurring.
