A system and method that scrambles the phase characteristic of a multicarrier signal are described. The scrambling of the phase characteristic of each carrier signal includes associating a value with each carrier signal and computing a phase shift for each carrier signal based on the value associated with that carrier signal. The value is determined independently of any input bit value carried by that carrier signal. The phase shift computed for each carrier signal is combined with the phase characteristic of that carrier signal so as to scramble the phase characteristic of the carrier signals. Bits of an input signal are modulated onto the carrier signals having a scrambled phase characteristic to produce a transmission signal with a reduced PAR.

L'invention concerne un système et un procédé permettant de brouiller la caractéristique de phase d'un signal de porteuse. Le brouillage de la caractéristique de phase de chaque signal de porteuse comprend l'association d'une valeur à chaque signal de porteuse, et le calcul d'un décalage de phase pour chaque signal de porteuse, basé sur la valeur associée à ce signal de porteuse. La valeur est déterminée indépendamment de toute valeur de bit d'entrée portée par le signal de porteuse. Le décalage de phase calculé pour chaque signal de porteuse est combiné à la caractéristique de phase du signal de porteuse, de façon à brouiller sensiblement la caractéristique de phase des signaux de porteuse. Les bits d'un signal d'entrée sont modulés sur les signaux de porteuse qui présentent la caractéristique de phase sensiblement brouillée pour produire un signal de transmission présentant un rapport valeur de crête sur valeur moyenne réduit.
