A communication apparatus may include a demodulation unit, a waveform memory unit, a decoding unit, an encoding unit, a modulation unit, and a transmission unit. The demodulation unit demodulates a received signal to create a demodulated signal. The waveform memory unit stores the demodulated signal and a waveform of the demodulated signal. The decoding unit decodes the demodulated signal to create a decoded signal. The encoding unit encodes the decoded signal to create an encoded signal. The modulation unit modulates one of the encoded signal to create a modulated encoded signal and the demodulated signal to create a modulated demodulated signal. The transmission unit transmit one of the modulated encoded signal and the modulated demodulated signal according to a reception state of the received signal.
