Abstract
A wireless communication device avoids unnecessary reduction of transmission capacity of a data signal to ensure the reliability of a pilot signal. A determination unit determines a reception modulation method for a received data signal according to the state of the transmission line. A transmission circuit generates a first pilot signal indicating the reception modulation method determined by the determination unit and, after adding an error correction code, modulates and transmits the first pilot signal. A reception unit receives a second pilot signal indicating a transmission modulation method that is the method for modulating a transmitted data signal. A switching unit, in accordance with the transmission modulation method indicated by the second pilot signal received by the reception unit, switches at least one of the modulation method of the first pilot signal transmitted by the transmission circuit and the redundancy of the error correction code of the first pilot signal.
