Abstract: The invention is directed to systems and methods for quadrature spatial modulation in the transmission of over a wireless network. 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.

Abstract: Representing vehicles in a customizable virtual environment is disclosed. One embodiment includes a controlled environment including prototype vehicles and a virtual environment including virtual representations of the prototype vehicles. The virtual environment is a display that includes an environment scenario, a number of virtual objects, and the various represented vehicles. The represented vehicles are linked to the prototype vehicles by communicating kinematic data from the prototype vehicles to the virtual vehicles real-time. The positions of the represented vehicles are updated based on the communicated kinematic data such that the virtual environment is a realistic visualization of the prototype vehicles. In addition, the virtual environment is highly customizable.
