Estimating the term…
A method of receiving binary data sequences from one or more mobile UEs represented by SCMA signals transmitted to at least two RRHs, communicatively connected to a common BBU and serving the one or more mobile UEs from different directions, of a COMP radio communication system over an OTFS communication channel continuous time domain signals representing the SCMA signals transmitted from the mobile UEs are received at each RRH. After removing cyclic prefixes from the received time-domain signals an OTFS demodulation is performed on the received signals, and the resulting two-dimensional arrangements of information symbols in the delay-Doppler domain are subjected to a centralized or to a decentralized signal detection and recovery, both of which perform an iterative Gaussian approximation expectation propagation process on the information symbols. The detected symbols are de-mapped for recovering the transmitted binary sequences of the respective mobile UE whose signals had been received.

A method of receiving binary data sequences transmitted, over an orthogonal time-frequency space modulation (OTFS) communication channel subject to doubly selective fading, from one or more mobile user equipments (UE) to at least two remote radio heads (RRH) of a co-ordinated multipoint radio communication system, the at least two RRHs being communicatively connected to a common base band unit (BBU) and being grouped to simultaneously serve a defined area, the at least two grouped RRHs being located remote from each other such that, at any time, each of the RRHs serves any one of the one or more mobile UEs from different spatial directions with regard to said respective UE's location within the defined area, such that a Doppler shift or spread of a signal transmitted from said respective UE that is received by at least one of the at least two grouped RRHs has an opposite sign than the corresponding signal received by one or more other of the at least two grouped RRHs, the method comprising:
A base band unit (BBU) of a co-ordinated multipoint radio communication system, comprising one or more antennas and associated transmitting and/or receiving circuitry, one or more microprocessors, volatile and non-volatile memory, which are communicatively connected via one or more signal or data lines or buses, wherein the non-volatile memory stores computer program instructions which, when executed by the microprocessor, configure the BBU to receive, from at least one of at least two RRHs that are communicatively connected to BBU, binary data obtained from detected and de-mapped signals received from one or more mobile UEs.
A base band unit (BBU) of a co-ordinated multipoint radio communication system, comprising one or more antennas and associated transmitting and/or receiving circuitry, one or more microprocessors, volatile and non-volatile memory, which are communicatively connected via one or more signal or data lines or buses, wherein the non-volatile memory stores computer program instructions which, when executed by the microprocessor, configure the BBU to receive, from at least one of at least two RRHs that are communicatively connected to BBU, symbols detected in signals received from one or more mobile UEs, and to de-map the received symbols, for obtaining binary data carried therein.
A computer program product comprising computer program instructions which, when executed by a microprocessor, cause a computer and/or control hardware blocks, modules or components of a base band unit (BBU) of a co-ordinated multipoint radio communication system comprising two or more remote radio heads (RRH) communicatively connected to the BBU, to receive, from at least one of the two or more RRHs, symbols detected in signals that are wirelessly received at the at least one RRH from one or more mobile user equipments (UE), and to de-map the received symbols for obtaining binary data carried therein.
A computer program product comprising computer program instructions which, when executed by a microprocessor, cause a computer and/or control hardware blocks, modules or components of a base band unit (BBU) of a co-ordinated multipoint radio communication system comprising two or more remote radio heads (RRH) communicatively connected to the BBU, to receive, from at least one of the two or more RRHs, binary data obtained from detected and de-mapped signals that are wirelessly received at the at least one RRH from one or more mobile UEs.
