PROBLEM TO BE SOLVED: To provide a digital wireless device with a reduced circuit scale that is applicable to a mobile wireless device using VHF and UHF bands and can perform highly reliable valid/invalid decision of a regenerated symbol clock without being affected by an artificial noise. SOLUTION: This digital wireless device consists of a wireless reception section 2 that converts a received radio wave into an intermediate frequency signal, a demodulation circuit section 3 that regenerates received data including a synchronous word and a symbol clock from the intermediate frequency signal, a synchronous word detection section 41 that detects a synchronous word from the received data and a synchronization establishment decision section 42 that decides synchronization establishment or out of synchronism from the synchronous word. |
