摘要:
The invention relates to a method for reducing peak values in single-carrier modulated or multi-carrier modulated digital transmitter signals, according to which the peak value is first determined from a plurality of sequential symbols contained in said digital signal. If a predetermined value is exceeded a replacement symbol is generated which replaces a predetermined transmitter symbol. The replacement symbol is selected such that it lowers the peak value and by means of a coding used to create the transmitter symbols can be converted error-free into the original transmitter signal.
