摘要： A method and apparatus are presented for transmitting a multicarrier signal, wherein said signal is of the offset quadrature amplitude modulation, OQAM, type comprising symbols in the time-frequency space, wherein the symbols include a data containing symbol and a precoding symbol, wherein the precoding symbol is selected such that the intrinsic interference at the data containing symbol, when received by a receiver, is forced to a value which ensures an applied space-time or space-frequency code. An Alamouti like space-time coding (or transmit diversity) is applied to a Filter Bank Multicarrier (FBMC) transmission using Offset QAM (OQAM). In FBMC, due to the orthogonality in the real domain only, an intrinsic interference results thereof for the imaginary component. The intrinsic interference terms are not equivalent at each antenna since it depends on the surrounding symbols. The application proposes to use only one precoding symbol per antenna such that the received signal at the data symbols is equivalent to a PAM Alamouti scheme, ie the precoding symbols condition the overall intrinsic interference to a given value compatible with the expected real PAM Alamouti scheme, reaching a rate loss of 1/3.

摘要： The receiver comprises a signal determiner, a soft information determiner and a soft information decoder. The signal determiner determines a complex receive value for the receive signal received from a relay station. Further, the soft information determiner obtains a soft information represented by a combination of a first probability value and a second probability value. The first probability value is derivable by adding a value depending on an overall probability density function for each symbol of a modulation alphabet comprising a same first bit value at a same bit position of the symbols, wherein each symbol of the modulation alphabet represents at least two bits. Further, the overall probability density function indicates a probability of receiving the complex receive value, if a signal representing the respective symbol s considered for adding was transmitted from a transmitter to a relay station, wherein the signal representing the respective symbol causes the receive signal received from the relay station. The second probability value is derivable by adding a value depending on the overall probability density function for each symbol of the modulation alphabet comprising a same second bit value at the same bit position of the symbols. Further, the soft information decoder decodes payload data contained by the receive signal based on the obtained soft information.

摘要： A method and apparatus are presented for transmitting a multicarrier signal, wherein said signal is of the offset quadrature amplitude modulation, OQAM, type comprising symbols in the time-frequency space, wherein the symbols include a data containing symbol and a precoding symbol, wherein the precoding symbol is selected to carry data in both the in-phase and quadrature components of the data containing symbol, when received by a receiver. An Alamouti like space-time coding (or transmit diversity) is applied to a Filter Bank Multicarrier (FBMC) transmission using Offset QAM (OQAM). In FBMC, due to the orthogonality in the real domain only, an intrinsic interference results thereof for the imaginary component. The intrinsic interference terms are not equivalent at each antenna since it depends on the surrounding symbols. The application proposes to use a precoding symbol chosen to cancel out (zero) the intrinsic interference individually for each antenna, ie a code rate of 1/2 (sending one data symbol requires two time units). A more elaborated embodiment proposes to choose the contiguous precoding symbols such that a virtual QAM Alamouti scheme is achieved, without rate loss.
