Abstract
A base station for a wireless communication system is capable of transmitting signals that match the polarization state of a mobile station by including an antenna arrangement having at least one set of transmit antenna elements and at least one set of receive antenna elements, a transformation mechanism having at least one antenna port coupled to the antenna arrangement and at least one beam port, and an adaptive measurement and control mechanism coupled to the transmit and receive antenna port signals and configured to measure and adaptively control attributes of the transmit and receive antenna port signals.
