ABSTRACT:
A peak suppression method detects a peak value exceeding a threshold value of a transmitting signal, forms a peak value prediction signal which is limited to a noise cancelling frequency band of a receiving end, based on the detected peak value of the transmitting signal, and subtracts the peak value prediction signal from the transmitting signal.
