ABSTRACT:
A transmitting device includes a setting unit dividing a transmitting frequency bandwidth into frequency blocks each narrower than a receivable bandwidth of a receiving device, and setting a transmission rate in each of the frequency blocks so as to increase or decrease stepwise, and a receiving device receiving signal with the transmission rate being thus set includes a receiving unit receiving the signal in any one of a plurality of receiving segments falling within the transmitting frequency bandwidth, each having the receivable bandwidth and provided so that at least one of the frequency blocks included in each receiving segment is also included in at least one of other receiving segments.
