Flexible structure for multiple-subcarrier joint modulation OFDM transmitters
An orthogonal frequency division multiplexing (OFDM) multiband transmitter (200) adapted to perform multiple-subcarrier-joint-modulation (MSJM) precoding. The transmitter comprises a bit interleaver (220) for independently interleaving bit blocks and grouping bits of each interleaved bit block to bit groups; a symbol mapping unit (230) for mapping each of the bit groups to symbols according to a MSJM scheme; and a symbol interleaver (240) for allocating the symbols to data subcarriers of a plurality of consecutive OFDM symbols.
