Abstract
A wireless communication apparatus for receiving a packet by detecting synchronization timing. The wireless communication apparatus includes: signal receiving means for receiving a transmission signal from a transmission source through an antenna; synchronization-timing detecting means for detecting synchronization timing using a timing detection field included in a header portion of the packet; synchronization-timing adjusting means for estimating and adjusting the amount of synchronization-timing shift detected by the synchronization-timing detecting means; and receive processing means for performing receive processing of the packet in accordance with the adjusted synchronization timing.
Claims16
A wireless communication apparatus for receiving a packet by detecting a synchronization timing, the wireless communication apparatus comprising:
- signal receiving means for receiving a transmission signal from a transmission source through an antenna;
- synchronization-timing detecting means for detecting a synchronization timing using a timing detection field included in a preamble of the received signal;
- synchronization-timing adjusting means for detecting whether or not the received signal has been subjected to a cyclic-shift and adjusting the synchronization timing detected by the synchronization-timing detecting means based on whether or not the received signal has been subjected to the cyclic-shift;
- and
- receive processing means for performing receive processing of the received signal based on the adjusted synchronization timing, wherein
- the synchronization-timing adjusting means detects whether or not the received signal has been subjected to the cyclic-shift based on information determined from the preamble of the received signal.
A method of wireless communication for receiving a packet by detecting a synchronization timing, the method comprising:
- receiving a transmission signal from a transmission source through an antenna;
- detecting a synchronization timing using a timing detection field included in a preamble of the received signal;
- detecting whether or not the received signal has been subjected to a cyclic-shift and adjusting the synchronization timing detected by the detecting step based on whether or not the received signal has been subjected to the cyclic-shift;
- and
- performing receive processing on the received signal based on the adjusted synchronization timing, wherein
- the detecting whether or not the received signal has been subjected to the cyclic-shift is based on information determined from the preamble of the received signal.
