Provided is a transmitter 1 for processing signals to be transmitted. The transmitter 1 reduces the peak power generated in a transmission signal, effectively, even in case a plurality of peaks exist, for example, in the transmission signal at positions (or times) close to each other. In the transmitter 1, coefficient generating means 35-39 and D1-DM detect the peaks of the levels of the transmission target signals, and generate a peak suppression coefficient for suppressing those detected peaks altogether on the basis of the peaks. Transmission target signal level suppressing means 40, 33 and 34 suppress the levels of the transmission target signals with the peak suppression coefficient generated.
