Abstract: The present disclosure relates to a transmitter device and a receiver device. The transmitter device comprises a processor which is communicably coupled with a transmitter unit. The processor is configured to receive a set of Z data streams and select K data streams with the same channel quality from the set of Z data streams for transmission, where K≤Z. Thereafter for each information word and for each data stream k=0, . . . , K−1 the processor encodes, scrambles and superposes so as to obtain a first signal sU. Further, for each information word and for each data stream k=0, . . . , K−1 the processor interleaves, encodes, scrambles and superposes so as to obtain a second signal sV. The first signal sU and the second signal sV are combined by the processor into a single signal s for transmission. The transmitter unit of the transmitter device is configured to transmit the transmission signal s over a radio channel.

Abstract: The invention relates to a transmitter device and a receiver device for efficient transmission of information messages. The transmitter device superposes a selected subset of columns of a projection matrix based on an information message so as to obtain a signal for transmission. The signal is transmitted to the receiver device. The receiver device performs iterative successive interference cancellation on a received signal based on a projection matrix so as to obtain a subset of the columns of the projection matrix and therefrom obtains a recovered information message based on the subset of the columns of the projection matrix. Thereby, it is provided a sparse superposition coding scheme with quasi-orthogonal projection matrix achieving good performance in respect of spectral efficiency. Furthermore, the invention also relates to corresponding methods and a computer program.

Abstract: A transmitter apparatus in a wireless communication system that includes a processor. In one embodiment, the processor is configured to receive at least one modulated data message and spread the at least one modulated data message into a transmission signal using a low density signature matrix. The low density signature matrix is a cycle-free signature matrix. A receiver apparatus is configured to receive the transmission signal and detect within the received transmission signal at least one modulated data message. The processor is configured to detect the at least one modulated data message in one iteration using the cycle-free signature matrix.

Abstract: Embodiments of the invention relate to a first communication device that maps a set of MIMO layers (M1, . . . , ML) into two or more subsets of MIMO layers (S1, . . . , SG)based on a modulation for each MIMO layer (Ml) and selects a modulation and coding scheme (MCS) for the set of MIMO layers (M1, . . . , ML) based on a code rate RC for a code word C and/or a modulation for a subset of MIMO layers (Sg). Further, the first communication device transmits the code word C on the set of MIMO layers (M1, . . . , ML) to a second communication device based on the selected MCS and transmits control information indicating the selected MCS and a result of the mapping of the set of MIMO layers (M1, . . . , ML) to the second communication device. The first communication device can thereby provide better protection of the systematic bits of the code word.

Abstract: A first communication device and a second communication device for an iterative code design are provided. The first communication device generates and transmits sets of parity symbols and receives the transmitted sets of parity symbols from a second communication device. The sets of parity symbols are generated based on using a first generator device and based previously transmitted systematic symbols and computed noise values. The second communication device buffers received systematic symbols and sets of parity symbols and jointly decodes them. Thereby, an iterative code design is provided with improved performance. Furthermore, the disclosure also relates to corresponding methods and a computer program.
