Abstract: A computer-implemented decoding method configures a plurality of transmit antennas to each represent an in-phase spatial constellation symbol within an in-phase spatial constellation, and a quadrature spatial constellation symbol within a quadrature spatial constellation, and maps source data to the in-phase spatial constellation symbols and the quadrature spatial constellation symbols represented by the plurality of transmit antennas, wherein the method constructs the set which has equal multiplicities of the transmit antenna activation, which ensures maximum possible transmit diversity.

Abstract: Scalable space-time quadrature spatial modulation for multidimensional wireless systems is performed by configuring a plurality of transmit antennas to each represent an in-phase spatial constellation symbol within an in-phase spatial constellation, and a quadrature spatial constellation symbol within a quadrature spatial constellation, mapping source data to the in-phase spatial constellation symbols and the quadrature spatial constellation symbols represented by the plurality of transmit antennas, wherein the method constructs the set which has equal multiplicities of the transmit antenna activation, which ensures maximum possible transmit diversity and reduces the required complexity, making this feasible for larger number of antennas.

Abstract: Configuring a plurality of transmit antennas to each represent an in-phase spatial constellation symbol within an in-phase spatial constellation, and a quadrature spatial constellation symbol within a quadrature spatial constellation, mapping source data to the in-phase spatial constellation symbols and the quadrature spatial constellation symbols represented by the plurality of transmit antennas, wherein the method is applying an optimal and scalable quadrature spatial modulation scheme (OS-QSM) resulting in a maximum possible coding gain in the resultant quadrature spatial modulation.
