ABSTRACT:
A method for reducing the peak-to-average power ratio (PAR) of a multicarrier signal in transmitter/receiver systems. The method comprises the steps of: providing, in transmission, a digital signal to be transmitted; and subjecting such a signal to be transmitted to a Fourier transform in order to obtain a modulated signal. It is characterized by the steps of generating an anti-peak signal; summing said anti-peak signal with said modulated signal; and transmitting the sum signal. The invention provides a transmitter and a receiver for implementing the method. Through the use of the invention, the PAR is reduced as compared with the known techniques.
