ABSTRACT:
A receiver estimates a channel quality. A transmitter amplifies a signal by a gain proportional to a difference between a required signal-to-noise power ratio and channel quality information, which is an estimation result of the channel quality, and transmits the signal so that the receiver can obtain the signal-to-noise power ratio. In this case, the receiver or the transmitter determines a roll-off rate of an adaptive filter based on the channel quality information. The transmitter uses the adaptive filter of the determined roll-off rate to filter and transmit the signal.
