    摘要: A method for performing a fast multiple-subcarrier-joint-modulation (MSJM) precoding. The method comprises grouping input information bits into bit blocks; converting the bit blocks into bit vectors; mapping a first group of bits of each bit vector to a real dimension of symbols in a symbol vector; mapping a second group of bits of each bit vector to an imaginary dimension of symbols in the symbol vector, wherein the mapping of the real dimension and the mapping of imaginary dimension are performed simultaneously; and modulating symbol vectors into data subcarriers.

    摘要: A method (400) for performing a multiple-sub-carrier-joint-modulation (MSJM) precoding. The method includes grouping input information bits into bit blocks (S410); converting the bit blocks into bit vectors (S420); mapping each of the bit vectors into a symbol vector (S430); and modulating symbol vectors into data subcarriers (S440).

    摘要: 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.
