Abstract (en)
[origin: WO0154230A1] A dynamically controlled polarization diversity system and method (100) for wireless communications comprises a transmitter, such as a base station (102), for transmitting signals with an adaptively controlled polarization state to a receiver, such as a mobile station (104). The polarization state may be adaptively varied by rotating a polarization angle, of the transmit signals. In one version, the polarization angle may be substantially continuously rotated from approximately 180 degrees to approximately 0 degrees in predetermined intervals. As the transmitter transmits signals with a varying polarization state, the receiver analyses the received transmit signals at the various states. The receiver may, for example, detect the received signal strength (RSSI) at each of the polarization states. The receiver then transmits a reply signal to the transmitter indicating the relative RSSI for each of the polarization states. The transmitter thereafter transmits at the polarization state which has the highest RSSI.
