  • Optimization of transmit signal polarization of an adaptive polarization array (APA)
    Patent number: 9258051
    Abstract: An Adaptive Polarization Array (APA) Algorithm is described for analyzing a wireless signal transmitted by an entity to determine a received polarization of the received wireless signal at a non-coherent receiver. The APA Algorithm determines a transmit polarization state for a transmitter to transmit signals to the entity based in part on the determined received polarization. The transmitter is an arbitrary-polarized transmitter configured to transmit signals at any polarization.
    Type: Grant

  • Adaptive polarization array (APA)
    Patent number: 8954023
    Abstract: An Adaptive Polarization Array (APA) Algorithm is described for adjusting the polarization orientation of antennas, such as Dual-polarized array antennas. The APA Algorithm searches to find a polarization state that maximizes a signal quality of a received signal in the presence of interfering signals and noise. The search facilitates adjustment of a polarization state of, for example, receive antennas to maximize a signal quality metric. A proxy metric having no local maxima other than the global maximum is used to search the polarization search domain to find a best polarization state.
