Abstract:
A transmitter wherein the peak power occurring in a transport signal can be efficiently suppressed. In this transmitter, a plurality of peak suppressing signal generating means (13,14,15) generate peak suppressing signals for suppressing the peak power of a transport signal. A peak suppressing signal combining means (16) combines the peak suppressing signals. A subtracting means (17) subtracts, from the transport signal, a combined resultant signal obtained by the peak suppressing signal combining means (16).
