Query: Transmit-Receive Generalized Spatial Modulation Based on Dual-layered
  MIMO Transmission   We propose a novel scheme for downlink multiuser multiple-input
multiple-output (MIMO) systems, called dual-layered transmit-receive
generalized spatial modulation (DL-TR-GSM). The proposed scheme is based on the
concept of dual-layered transmission (DLT) which uses two receive antenna power
levels instead of receive antenna activation/inactivation to transmit data in
the receive spatial domain. Hence, in order to minimize the bit error rate
(BER) for DL-TR-GSM, the optimal ratio between the two power levels is
determined. To further characterize DL-TR-GSM, we fully derive the
computational complexity and show a significant computational complexity
reduction as well as a required hardware complexity reduction of DL-TR-GSM,
compared to a state-of-the-art benchmark scheme. Simulation results confirm the
performance advantages of DL-TR-GSM.
