TRANSMITTER, RECEIVER, AND COMMUNICATION METHOD.

摘要

When the measurement of communication quality using a wideband signal is performed simultaneously with data transmission/reception using a predetermined frequency band, the quality deterioration of the data transmission/reception is prevented. A transmitter (1) is capable of performing the data transmission using first and second frequencies to a receiver (2). A transmission section (1a) of the transmitter (1) transmits a predetermined wideband signal in a frequency band except the first frequency in a first period and transmits the predetermined wideband signal in a frequency band except the second frequency in a second period. A measurement section (2a) of the receiver (2) measures the communication quality with the transmitter (1) according to the wideband signals received in the first and second periods.
