Abstract
A method and a system for transmitting data by a transmitter over a channel having a predetermined channel quality estimate, comprises the steps of splitting (SP) input data stream (S, S, S) to be transmitted into a plurality of data sub-streams (S, S, S); processing (SYM, SYM, SYMj) each of the plurality of data sub-streams (S, S, S) into a plurality of symbol subsets (S, S, S) by selecting a certain scheme of coded-modulation (BPSK, QPSK, 16-QAM); processing, separately, each of the plurality of symbol subsets (S, S, S), via a plurality of separate Discrete Fourier Transforms (DFT, DFT, DFT), herein after denoted as DFTs, to obtain a plurality of DFT-precoded data sub-streams (S, S, S); allocating each DFT-precoded data sub-stream (S, S, S) in a frequency resource block (RB, RB, RB), via a sub-carrier mapping module (SCM), so that for each data sub-stream (S, S, S) the selected scheme of coded-modulation (BPSK, QPSK, 16-QAM) is chosen in dependence of the values of the channel quality estimate at the frequencies of its own allocated frequency resource block (RB, RB, RB).
