Patent number: 7474723Abstract: A DSRC communication technology that prevents unique word detection errors even when the frame changes in data reception and the timing of the unique word detection window and the timing of the received data do not match, and that adjusts the data transmission timing in a flexible fashion when the slot timing deviates from the frame timing. In this technology, bit counter 111 generates the frame timing from the frame synchronization signal, and bit counter 112 generates the sot timing in response to the slot synchronization signal. The unique word detection window is generated from the frame timing and the received data operation timing and the data reception timing are generated from the slot timing. In addition, the data transmission timing and the transmission data operation timing are generated based on one of the frame timing and the slot timing chosen in selector 123.Type: GrantFiled: April 1, 2005Date of Patent: January 6, 2009Assignee: Panasonic CorporationInventor: Shigeki Oyama
