Abstract
The major problem in multicarrier transmission procedures consists in the very high crest factor of the transmit signal. This means, that very high signal peak values occur even with a moderate transmission power. It is the object of the invention to provide a method and device, whereby a definite reduction of signal peaks is achieved with moderate expenditure. This is obtained by generating, in addition to the information to be transmitted, several alternative, information-equivalent information sequences by means of determined reversible unambiguous representations. From these alternatives a sequence being favorable in view of the peak value of the pertinent transmit signal is selected and transmitted. The receiver is in a position to regenerate the original information from said receiving signal through the inversion of the performed representation.
