Synchronization circuit, synchronization method, wireless communication apparatus, wireless communication method, and computer program
Abstract:
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.
Abstract(Chinese):

同步电路包括分组检测单元，其对接收到的信号进行搜索，将前导码添加到分组的开始处，并且包括给定的重复训练序列以检测分组; 分组检测再确认单元，在分组检测单元已经检测到分组的场之后，通过使用前导码中的字段中的接收信号来再次确认分组检测单元的分组检测; 以及控制单元，其响应于分组检测再确认单元来消除分组检测单元的分组检测，所述分组检测再确认单元检测分组检测单元对分组的错误检测，以使分组检测单元从接收信号开始检测分组 再次。
