Abstract:
Disclosed is a transmission device including a plurality of antennas for transmitting signals in the same channel at the same time point to a plurality of reception devices, characterized by including: a DRS generator configured to generate DRSs (dedicated reference signals) for the respective reception devices; a nonlinear spatial multiplexer configured to generate a nonorthogonal DRS by use of a first group of DRSs including at least one of the DRSs; and a transmitter configured to transmit a signal containing at least the nonorthogonal DRS.
