Description
Receiver, transmitter, method and system for receiving and , , transmitting a combination signal Filing Date 21 02 2019 FIELD AND BACKGROUND OF THE INVENTION Technical Field Embodiments of the invention describe apparatuses and methods for multi-user communication.
Background of the Invention In digital information transmission, two or several similar data-carrying message signals oftentimes additively overlap in the transmission path, or are already output as overlapped signals by a transmitter. As long as a separability of the signals is ensured by the use of a multiplex method on the transmitter side, e.g. by using different frequency ranges (Frequency Division Multiplex: FDM), disjoint time slots (Time Division Multiplex: TDM), different codes (Code Division Multiplex Access: CDMA) or different spatial propagation directions and their resolution by several spatially separated receiving antennas (Space- Division Multiple Access through MIMO transmission: SDMA), this does not present any problem and has been the state of the art since the beginning of electrical communications engineering. This situation becomes more complicated if signals overlap uncoordinatedly in the same frequency band. As long as the reception signals differ significantly in terms of reception power, transmission rates (bit/symbol) and/or their power efficiency, successive demodulation, detection and decoding are oftentimes possible, i.e. detecting the strongest signal and subtracting it from the received sum signal after recoding and remodulation based on the detected data. Under certain boundary conditions, this approach may even represent an information-theoretically optimum solution [8]. In the case of less pronounced differences in the reception powers and/or power efficiencies of the individual signals, an iterative approach is recommended, wherein a partial subtraction of interfering signals that corresponds to the estimated probabilities of the data symbols is performed, and a manifestation of the probabilities should occur in favor of only one data symbol at a time in several iteration steps. In the case of signals of almost the same strength and power efficiency, only the use of an optimum multi-user receiver is usually a viable option. The overlapped signals are interpreted as one signal that, per modulation step, represents all data symbols - 2 - corresponding to the overlap of the individual signals. In the case of identical modulation methods for
