An active antenna, a base station, a method for refreshing the amplitude and phase, and a signal processing method are disclosed to simplify the structure of a phase shifter and guarantee the reliability of the phase shifter. The active antenna or the base station includes an antenna dipole array, a transceiver array, a digital processing unit (DPU), and a transceiving calibration unit. During signal reception, the transceiver demodulates a radio frequency (RF) signal of the antenna dipole into an IQ analog signal, and outputs the IQ analog signal to the DPU; the DPU converts the demodulated IQ analog signal into an IQ digital signal, and performs digital beam forming (DBF) on the IQ digital signal according to the transceiving calibration unit; during signal transmission, the transceiver modulates the IQ analog signal of the DPU into an RF signal, and outputs the RF signal to the antenna dipole; the DPU converts a signal of a base band unit (BBU) into an IQ digital signal in serial/parallel (S/P) mode, and performs DBF on the IQ digital signal according to the transceiving calibration unit.

The present invention discloses a method for checking MA integrity, including: creating an MEP a; determining, by an MEP c in an MA, whether an MEP b with the same source port information as the MEP a exists in the MA; if there exists an MEP b with the same source port information as the MEP a in the MA, no isolated and unmated MEP exists in the MA; if an MEP b with the same source information as the MEP a does not exist in the MA, an isolated MEP exists in the MA. The present invention also discloses an apparatus for checking an MA integrity and a method and an apparatus for adding an MEP. The present invention enables a user to know whether an MA is integral and ensures MA integrity.
