Patent ID: 7783311

Claim:
A receiving station for receiving information from one or more transmitting stations, comprising: a receiving unit configured to receive information containing a unique value of the transmitting station; an extracting unit configured to extract the unique value from the received information; a clock generation unit configured to generate clock information; a memory configured to store a transmit timing sequence in association with each of the one or more transmitting stations, the transmit timing sequences consisting of a plurality of codes to identify plural different time slots for transmission; a transmit timing sequence acquiring unit configured to acquire the transmit timing sequence of the transmitting station from the memory based on the extracted unique value; a control unit configured to determine whether a code value corresponding to a currently focused code number of the transmit timing sequence corresponds to the clock information; and a synchronizing unit configured to bring receive timing of the receiving station in synchronization with transmit timing of the transmitting station if the code value corresponds to the clock information.
