Further embodiment for compensation of such common phase rotations are provided, in which means are adapted to rotate the baseband symbols such that the passband frequency signal is complying with the DVB - C2 standard. The present invention relates to OFDM generation apparatus and methods for generating OFDM transmission signals (s(t)) from OFDM symbols, each comprising a plurality of OFDM subcarriers, for transmission in a multi-carrier data transmission system.

摘要： In a communications device (100) a grouping unit (152) uses channel state information when mapping data bits to a plurality of different constellation groups. Each constellation group is assigned to another modulation scheme. A plurality of sub-carriers is assigned to none or one of the constellation groups and each modulation uses another one of the constellation groups. The communications device (100) may include a plurality of scalable interleaver units (156), wherein each interleaver unit (156) is assigned to one of the constellation groups and interleaves the assignment of data bits mapped to each constellation group and the sub-carriers that carry a symbol information derived from the data bits. For example, the interleaver unit (156) performs frequency interleaving by interleaving, at constellation level, the sub-carriers that carry the symbol information.
