Résumé:
We propose a further generalization of spatial
modulation (SM) in a downlink multiuser MIMO system with
multicast in order to improve the system’s spectral and energy
efficiencies. A base station equipped with multiple antennas
sends three types of information to several users also equipped
with multiple antennas. The individual information to each user
is conveyed in the form of receive SM as well as through
conventional QAM modulation. On top of that, common transmit
SM information is conveyed to all users. To this end, specific
preprocessing and postprocessing are obtained based upon the
singular value decomposition technique. A simple additional processing
based on phase shifts is proposed to improve detectability.
Computer simulation results reveal that the proposed scheme has
improved average bit-error rate (BER) over a reference scheme
under the same spectral efficiency
