摘要
The present invention concerns a method of mapping chips of a spread out symbol to sub-channels of a group of sub-channels of a Multi-Carrier transmission channel of a Multi-Carrier transmission network, the spread out symbol being formed by multiplying a data item to be transmitted by elements of a spreading sequence, the mapped chips being further modulated using an orthogonal frequency division multiplexing modulation, each sub-channel of the Multi-Carrier transmission channel being defined by a carrier frequency of the Multi-Carrier transmission channel and a time slot wherein an orthogonal frequency division multiplexing symbol is transmitted, characterised in that the chips are ordered in a predetermined order, the first chip is mapped to a sub-channel and each following chips are mapped to a sub-channel which has the same carrier frequency or the same time slot as the sub-channel of which the previous chip has been mapped to. The method concerns also a method the de-mapping and associated devices.
