Abstract:
1. A wireless communication apparatus for bidirectional wireless communication, comprising: a reception section configured to receive a wireless transmission signal and produce therefrom a reception signal; a first oscillator configured to produce a signal having a frequency upon which reception processing is based, where the reception signal is injected into the first oscillator; a frequency locking detection unit configured to detect whether the frequency of the signal of the first oscillator is frequency locked with a carrier frequency of the reception signal, wherein, if the frequency locking detection unit detects that oscillation frequency of the signal of the first oscillator is frequency-locked with the carrier frequency of the reception signal, the wireless communication apparatus transmits a communication enable signal; and a control unit, wherein the first oscillator is configured to produce a signal having a free-running oscillation frequency, and the control unit is configured to vary the free-running oscillation frequency of the first oscillator.
