摘要： 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.
