Dual carrier modulation precoding

A computer-readable medium having stored thereon computer executable code for performing dual carrier modulation (DCM) precoding, comprising:

• generating data sub-blocks (S320);
• independently interleaving the generated sub-blocks (S330);
• generating bit vectors by grouping bits of the interleaved sub-blocks (S350);
• mapping the bit vectors into data symbols (S360);
• and
• precoding the data symbols using a precoding matrix to generate precoded symbols (S370).

An orthogonal frequency division multiplexing (OFDM) transmitter (100) for performing a dual carrier modulation (DCM) precoding, comprising:

• a bit interleaver (130) for interleaving sub-blocks including encoded input information bits;
• a constellation mapping unit (140) for generating bit vectors from the interleaved subblocks and mapping the bit vectors to information symbols, wherein the constellation mapping unit (140) is further capable of precoding the information symbols using a precoding matrix to generate precoded information symbols;
• and
• a symbol interleaver (150) for distributing the precoded information symbols into different data subcarriers of a plurality of OFDM symbols.
