The invention relates to a method for controlling a combined waveform. The combined waveform represents a combination of at least two signals having orthogonal frequency multiplexing signal components. The method comprises the steps of: receiving information defining the at least two signals; converting the information defining each signal into representation having the orthogonal frequency multiplexing signal components, so that at least one signal has at least two replacement representations having the same information, and combining the converted information by using the at least two replacement representations in at least two different manners, so that respectively different combinations are defined; for at least one standard, analyzing the respectively different combinations; and outputting the corresponding combined waveform or information defining the waveform, wherein it represents a combination selected based on the converted information of each one in the at least two analyzed and selected signals.
