MULTI-POLARIZATION TRANSMITTING/RECEIVING ANTENNA, AND TRANSMITTING/RECEIVING APPARATUS, SYSTEM AND METHOD

摘要

Provided are a multi-polarization transmitting/receiving antenna, and a transmitting/receiving apparatus, system and method. A multi-polarization transmitting antenna comprises: M transmitting orthogonal antenna arrays, wherein each transmitting orthogonal antenna array comprises a pair of mutually polarized orthogonal dual polarization antennas, M being an integer greater than or equal to 2; and a transmitting mode and/or an antenna polarization direction of the M transmitting orthogonal antenna arrays being adjusted according to a condition number of a channel matrix fed back by a receiving end. While improving the multiplexing and diversity gain, the embodiments of the present invention lower the requirement on an inter-antenna distance and improve the reliability of transmission.
