A plurality of transmit antennas are configured in a spaced apart configuration, with each antenna representative of a spatial constellation symbol comprising an in-phase component and a quadrature component. A transmission unit is configured to map source data to the spatial constellation symbol of the transmit antennas, and to transmit a carrier signal comprising the in-phase and quadrature components out of phase. At least one receiving antenna is configured to receive the carrier signal, and at least one receiving unit is configured to demodulate the carrier signal to generate the source data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Quadrature spatial modulation system","description":"The invention is directed to systems and methods for quadrature spatial modulation in the transmission of over a wireless network.
