| 20090103516 | SYNCHRONIZATION DETECTING CIRCUIT AND MULTIMODE WIRELESS COMMUNICATION APPARATUS - Multimode wireless communication apparatus supports plural wireless communication methods and includes synchronization detecting part. Digital signals output from first A/D part and second A/D part are combined by synchronization detecting part. Synchronization detecting part converts sampling frequencies of respective digital signals and performs other processes when combining digital signals. Synchronization detecting part detects synchronization timing for plural wireless communication methods by plurally performing correlation operation corresponding to respective wireless communication methods for digital signals combined, thereby providing a multimode wireless communication apparatus with its size and power consumption reduced. | 04-23-2009 |
