摘要：The transmission system according to the invention comprises a transmitter (10)and a receiver (12). The transmitter (10) can transmit datawords via a multicarrier signal(11) to the receiver (12). In order to reduce the crest factor of this multicarrier signal (11)the transmitter (10) comprises a generator (20) and a selector (22). The generator (20)generates for each dataword (19) a number of alternative sequences (21) by combiningmutually different digital words with the dataword (19). For this purpose, the generator(20) may comprise an augmentor (40) and a scrambler (42). The augmentor (40)
generates for each dataword (19) a number of intermediate sequences (41) by combiningthe digital words with the dataword (19). These intermediate sequences (41) arescrambled by the scrambler (42) in order to form the alternative sequences (21). Fromthese alternative sequences (21) the alternative sequence with the lowest peak powervalue (23) is selected for transmission to the receiver (12).
