A wireless communication apparatus for performing communication using a first communication scheme which transmits a signal using amplitude shift keying and a second communication scheme which suppresses communication with others except a communication counterpart by transmitting a transmission suppression signal before communication is started. The apparatus includes: a first signal generation unit configured to generate transmission data; a modulation unit configured to generate first and second signals having different amplitudes by amplitude-shift keying the transmission data; a second signal generation unit configured to generate the transmission suppression signal having a signal length corresponding to that of the first signal; and a transmission unit configured to transmit the transmission suppression signal at the timing when the first signal is transmitted.
