Abstract
A transmitter, that effectively suppresses a peak level of transmit signals, equipped with a peak reduction signal generating means that generates a peak reduction signal. A level of the peak reduction signal is based on a transmit signal level threshold for determining a peak of the transmit signal, and is based on a transmit signal peak level. Further, a phase of the peak reduction signal is based on the phase of the transmit signal. The transmitter is also equipped with a peak reduction signal processing means that subjects the peak reduction signal to band restriction and orthogonal modulation, and is equipped with a transmit signal level suppressing means that subtracts the peak reduction signal subjected to band restriction and orthogonal modulation from the transmit signal.
