Synchronization Circuit, Synchronization Method, Wireless Communication Apparatus, Wireless Communication Method, and Computer Program

摘要

A synchronization circuit includes a packet detecting unit that searches a received signal for a preamble that is added to the beginning of a packet and that includes given repetitive training sequences to detect the packet; a packet detection reconfirming unit that reconfirms the packet detection by the packet detecting unit by using a received signal in a field in the preamble, subsequent to the field where the packet detecting unit has detected the packet; and a control unit that cancels the packet detection by the packet detecting unit in response to the packet detection reconfirming unit that detects erroneous detection of the packet by the packet detecting unit to cause the packet detecting unit to start detection of a packet from a received signal again.
