  • Spatial modulation method and transmitting and receiving apparatuses using the same in a multiple input multiple output system
    Publication number: 20080037673
    Abstract: A spatial modulation method and transmitting and receiving apparatuses using the spatial modulation method in a MIMO system are provided. The spatial modulation method uses an index of an activated antenna and a signal modulation constellation as an information source. The spatial modulation method is applied to the transmitting apparatus. The receiving apparatus uses a spatial modulation detection method in which a channel path gain is repeatedly multiplied to detect the spatially modulated signal efficiently.
