Abstract:
1. A method of up-converting a baseband signal to a given number of frequency bands, the method comprising defining a temporal order in which the frequency bands are to be used for up-converting the baseband signal, the frequency bands having a spectral order defining a signal transmission channel; and up-converting the baseband signal to the respective frequency band in the defined temporal order, wherein the spectral distance between two frequency bands is equal or higher for the frequency bands which are direct neighbors in the defined temporal order than for frequency bands which are direct neighbors in the spectral order, and wherein the temporal order is defined by, for each frequency band, selecting a subsequent frequency band based on which of the frequency bands satisfies a condition that an average spectral distance between center frequencies of any two direct consecutively arranged frequency bands in the temporal order is maximum.
