摘要： To lessen a disparity in stream mapping of transmission data when modulation data are mapped into a plurality of streams and when the plurality of streams are transmitted and received. In a wireless communication device, a stream mapper (14) that performs mapping into a plurality of streams sequentially maps a modulation symbol sequence output from a modulator (13) into a plurality of streams for each block output from a channel interleaver (12) that performs channel interleaving, such as sub-block interleaving. On this occasion, a stream mapping method is changed in predetermined unit commensurate with a block size; for instance, at each position of a sub-block length where sub-block interleaving is performed or at each position of a half sub-block length.

摘要： The invention relates to method and apparatus for generating modulation symbols according to a second symbol mapping scheme by a symbol mapping unit being adapted to generate symbols according to a first symbol mapping scheme, wherein the first and second symbol mapping schemes define different mappings of data words of a stream to modulation symbols of a modulation scheme according to the respective symbol mapping scheme. Further, the invention relates to a method and apparatus for generating a mapping of data words to modulation symbols of a square 16 QAM constellation, the modulation symbols being representable by an inphase component and quadrature component. One aspect of the invention is the introduction of a bit sequence transformer unit transforming the data words to be mapped to modulation symbols prior to mapping thereby changing the Hamming distance properties of the mapping. Another aspect of the invention is the generation of a new AICO (Antipodal Inverted COnstellation) mapping scheme.

摘要： Transmit diversity system in which constellation rearrangement is used. Both diversity signals contain the same data and both are 16-QAM, but the location of the data bits within the constellation is different. This averages the effect of the different levels of reliability of the different constellation points. A method for modifying a quadruple of data bits in a data transmission system using Quadrature. Amplitude Modulation with 16 different modulation states, 16-QAM, using an Antipodal Inverted Constellation AICO) mapping, swapping bits selecting contiguous symbol regions with bits selecting non-contiguous symbol regions. Depending on the particular pre-defined mapping and on the particular permutation of bits, inversion of selected bits may be performed in addition. The quadruples thus obtained are mapped to modulation symbols according to a pre-defined AICO mapping. In the corresponding method for receiving the symbols, likelihood values are swapped and modified in a way which is complementary to the permutation and inversion of bits, before they are combined with likelihood values from other symbols representing the same bits. Method ensures that there is a one to one correspondence between Hamming distance and Euclidian distance for the combined received data. In other words it ensures that, once combined, all 4 bit data words which differ by the same number of bits (Hamming distance) are the same distance apart in the constellation (Euclidian distance).

摘要： Provided is a MIMO transmission device which can effectively perform a pilot transmission by using a surplus sample generated in a pilot symbol while maintaining the pilot separation accuracy at a reception side. The MIMO transmission device (100) transmits a pilot symbol as follows. That is, in a first pilot transmission symbol section, a transmission section of a pilot signal transmitted from a first transmission antenna is partially overlapped by a pilot transmission section of a second transmission antenna. In a second pilot transmission symbol section, a pilot transmission section of the first transmission antenna is partially overlapped by a pilot transmission section of a third antenna. Among the pilot signals transmitted from the first antenna, the interference portions overlapped by transmission pilot signals from other antennas are different between the first pilot transmission symbol section and the second pilot transmission symbol section.
