Abstract

The invention relates to a method and a device for transmitting information symbols using a plurality of carriers, wherein a first transmission symbol is produced (52, 54) on the basis of an information symbol. A second transmission symbol is also produced (52, 54) on the basis of the same information symbol, wherein the second transmission symbol differs from the first transmission symbol. The first and second transmission symbols are modulated (56) on a carrier and transmitted (62) at different intervals. The invention further relates to a method and a device for receiving information symbols represented by the first and second information symbols, wherein both transmission symbols received are used in order to extract the information symbol contained in both transmission symbols.
