Abstract
The wireless reception device has automatic frequency control unit for detecting, from a reception modulation signal frequency-converted to the baseband, a frequency deviation component of a carrier wave between transmission and reception sides that is contained in the reception modulation signal and removing the frequency deviation component from the reception modulation signal, the automatic frequency control unit having a frequency locking operation state and a steady state following the frequency locking operation. The wireless reception device further has modulation component removal unit for generating a synchronization detection reference signal by removing the modulation component of the received modulation signal; and match detection unit that detects a mismatch between the synchronization detection reference signal and the frequency deviation component detected by the automatic frequency control unit, wherein, when the match detection unit detects the mismatch, the automatic frequency control unit are controlled to the frequency locking operation state.
