    摘要: To satisfy the required SNR values for each system and/or each channel, a peak factor reduction device for reducing peak components included in a transmission signal, generates a cancellation signal to be multiplexed on the transmission signal, and the peak factor reduction device changes an amplitude of the generated cancellation signal according to a signal noise ratio required for the transmission signal and a power level of the transmission signal.
