Patent ID: 7697593

Claim:
A receiving apparatus, comprising: a receiver which receives a packet signal wherein the packet signal is such that a first data signal is assigned posterior to a first known signal, a second known signal is assigned posterior to the first data signal, and a second data signal is assigned posterior to the second known signal; a first detector which detects a temporary timing in a manner such that the presence of the first known signal in the packet signal is detected by performing correlation processing on the first known signal in the packet signal received by said receiver; a first processing unit which detects the presence of the second known signal in the packet signal, by processing the first data in the packet signal at the temporary timing detected in said first detector; a second detector which detects a timing by performing correlation processing on the second known signal in the packet signal received by said receiver when the presence of the second known signal is detected by said first detector; and a second processing unit which processes the second data signal in the packet signal, at the timing detected by said second detector, wherein an identical pattern is contained both in the first known signal and the second known signal in the packet signal received in said receiver.
