The present invention relates to a transmitter device and a receiver device. The transmitter device 10 comprises a processor 11 which is communicably coupled with a transmitter unit 12. The processor 11 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 11 encodes, scrambles and superposes so as to obtain a first signal s U . Further, for each information word and for each data stream k = 0,..., K — 1 the processor 11 interleaves, encodes, scrambles and superposes so as to obtain a second signal s v . The first signal s U and the second signal s V are combined by the processor 11 into a single signal s for transmission. The transmitter unit 12 of the transmitter device 10 is configured to transmit the transmission signal s over a radio channel of the wireless communication system 30. The receiver device 20 comprises a receiver unit 21 and a processor 22 configured to decode the transmitted signal. Furthermore, the present invention also relates to corresponding methods, a computer program, and a computer program product. |
