A method for optimizing reception of a polarized single-carrier transmission, including transmitting a polarized single-carrier transmission to a receiver, receiving feedback from the receiver of a figure of merit of the polarized single-carrier transmission, and electronically changing polarization of the polarized single-carrier transmission based on the feedback. A single-carrier communication transmitter including a source for a polarized single-carrier transmission signal, a circuit for receiving feedback from a receiver describing a figure of merit of a received polarized single-carrier transmission, and a circuit for changing polarization of the polarized single-carrier transmission signal, based on the feedback. Related apparatus, systems and methods are also described.
