Abstract: Provided is a communication device capable of lengthening a transmission distance without degrading communication quality and capable of suppressing the erroneous recognition of received data. The communication device comprises: a transmission unit (24) for generating a data stream signal on the basis of the transmission data in a transmission buffer (23) and transmitting through a transmission medium to the other party's device; an adaptive equalizer (25) for adjusting the waveform of a stream signal on the transmission medium on the basis of the transition time of a data bit; and a receiving unit (26) for extracting received data from the stream signal after the waveform adjustment. In a transmission phase, the transmission unit (24) transmits a preamble stream signal and then starts to transmit the data stream signal. In a reception phase, the adaptive equalizer (25) adjusts the waveforms of the preamble stream signal and the data stream signal from the other party's device, and the receiving unit (26) extracts the received data from the data stream signal inputted via the adaptive equalizer (25).
