Abstract:
1. A method for reducing the dynamic range of a multicarrier transmission signal which is formed in a transmitter and is composed of at least two carriers, with each carrier having specific associated signal streams, and the signal streams having the same repeating signal structure, wherein the signal structure is a frame or a time slot or a chip group, and wherein, for the at least two carriers, signal streams which are associated with the same carrier have a common signal structure timing, the method comprising: determining at least one time of a signal structure boundary for each of the at least two carriers; determining a delay for each of the at least two carriers based on the times of the signal structure boundaries; delaying all the signal streams which are associated with one carrier using the delay determined for the carrier such that non-random signal sections of identical signal values of signal streams associated with different carriers are not aligned in time with respect to one another; and producing the multicarrier transmission signal by combination of the signal streams of the carriers, wherein the delay results in identical signal values of at least two non-random signal sections associated with the at least two carriers not being superimposed on one another so they do not add constructively in the multicarrier transmission signal.
