Abstract
Provided is an apparatus and method for transmitting and receiving polarized signals. Wireless communication with multiple polarized signals may experience greater attenuation on one polarized signal than another polarized signal. The polarized signal that is more attenuated limits overall throughput for the wireless communication. According to an embodiment of the invention, signals undergo rotation processing with a transformation involving a rotation matrix prior to transmission. Each polarized signal that is transmitted is based on a different weighted combination of the signals. The rotation processing can be performed with an objective that signals recovered at a receiver have comparable signal quality, which can increase overall throughput. In some implementations, the rotation processing is performed based on feedback to dynamically adjust the rotation processing.
