Abstract
The invention relates to a data transmission method in which the data to be transmitted are divided into a plurality of subchannels each with a normal component and a quadrature component that is orthogonal to the normal component. The divided data are transmitted in different frequency bands. The frequency bands are arranged with non-equidistant frequency spacings between one another. An error signal is generated at the reception end for each subchannel both for the normal branch and for the quadrature branch and fed to a corresponding reception filter.
