SUBSTANCE: disclosed invention relates to a transmitting apparatus, a receiving apparatus and a data transmitting method. To this end, measurement of communication quality using a broadband signal and transmitting and receiving data using a predetermined frequency band is carried out at approximately the same time. The transmitting apparatus (1) can transmit data at a first frequency and a second frequency to the receiving apparatus (2). The transmitter (1a) of the transmitting apparatus (1) transmits a predetermined broadband signal in a first period of time in a frequency band which does not include the first frequency, and in a second period of time in a frequency band which does not include the second frequency. The quality measuring unit (2a) of the receiving apparatus (2) measures quality of communication with the transmitting apparatus (1) based on the broadband signal received in the first and second period of time.
