Abstract
A transmitting apparatus is capable of transmitting data at a first frequency and second frequency to a receiving apparatus. A transmitter of the transmitting apparatus transmits a predetermined wideband signal, in a first time period in a frequency band which does not include the first frequency and in a second time period in a frequency band which does not include the second frequency. A quality measuring unit of the receiving apparatus measures the quality of communication with the transmitting apparatus based on the wideband signal received in the first and second time periods.
