<P>PROBLEM TO BE SOLVED: To provide a mobile wireless communication apparatus or the like capable of quickly establishing a communication link by reducing the length of a synchronous word and detecting synchronization with excellent accuracy. <P>SOLUTION: The mobile wireless communication apparatus acquires the synchronization by using both a pre-word PW and the synchronous word SW or acquires the synchronization by using only the synchronous word SW in response to the operating state with respect to the synchronization. For example, the communication apparatus uses both of the pre-word PW and the synchronous word SW and regards it that the synchronization is established when an arithmetic result in a synchronization arithmetic section exceeds a prescribed threshold value only once in the case that a control channel 110 is a reception object and the state of the communication apparatus is an initial synchronizing state, and the communication apparatus uses both of the pre-word PW and the synchronous word SW and regards it that the synchronization is established when the arithmetic result in the synchronization arithmetic section exceeds the prescribed threshold value only once or uses only the synchronous word SW regards it that the synchronization is established when the arithmetic result exceeds the prescribed threshold value consecutively twice in the case that a direct communication channel 112 is a reception object and the state is an initial synchronizing state. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
