| 摘要 |
Embodiments of the present invention provide a base station comprising an antenna unit and a radio frequency unit; the port corresponding to the reception channel in working state in the radio frequency unit and the port corresponding to the transmission channel in working state in the radio frequency unit, respectively connect with the ports corresponding to different dual polarization oscillators or different single polarization oscillators in the antenna unit, and the different dual polarization oscillators or different single polarization oscillators in the antenna unit are isolated from each other. Regardless in same frequency band or in different frequency bands, the embodiments of the present invention can solve the interference to uplink signals from intermodulation signals generated by downlink signals. |
