| 摘要 |
Embodiments of the present invention provide a base station, including an antenna unit and a radio frequency unit, where a port corresponding to a receive channel that is of the radio frequency unit and in a working state and a port corresponding to a transmit channel that is of the radio frequency unit and in the working state are separately connected to ports corresponding to different dual-polarized dipoles or different single-polarized dipoles in the antenna unit, where the different dual-polarized dipoles or the different single-polarized dipoles in the antenna unit are mutually isolated. The embodiments of the present invention can eliminate interference of an intermodulation signal generated by a downlink signal to an uplink signal for both a same frequency band and different frequency bands. |
