Method and device for mixing N information signals

A method of mixing N information time signals which are respectively converted from the time domain to the frequency domain into one of N complex information signals, where N is an integer greater than 1, the method comprising the steps of:

• (a) spectral values of the N complex information signals which match in a frequency are each converted into a corresponding first and a second component, wherein each of the first and second components for each of the respective spectral values are selected such that they would yield the respective spectral value if a complex value addition of the first and second component were performed,
• (b) the N first components of the N frequency-matching spectral values are combined into a first combination component,
• (c) the N second components of the N frequency-matching spectral values are combined into a second combination component,
• (d) the first combination component and the second combination component are combined into a result spectral value,
• (e) the steps (a) to (d) are also performed for other frequency-matching spectral values of the N complex information signals for generating other result spectral values,
• (f) wherein the obtained result spectral VALUES form a complex output information signal.
