- W4308650963 abstract "This paper proposes a multi-channel synchronization method for multi-antenna wireless communication systems., including the calibration of the transmit channels and the calibration of the receive channels. In particular., the calibration of the transmit channels and receive channels use an antenna array., respectively. Based on the transmitted signals with specific amplitude and phase., the received signals are first analyzed by extracting the feature from signals. Then., we use the analysis results to obtain the amplitude and phase calibration factors of the transmit channels and receive channels. Next., we apply the calibration factors to the digital part in order to compensate the amplitude and phase offset of the radio frequency (RF) module., thus the channel consistency is achieved. Compared with the RF local oscillator power division networks., the proposed channel synchronization method only needs to simply modify the calibration settings in the case of increasing or decreasing the number of channels., which greatly improves the flexibility of systems. Simulation results show that this method can compensate the amplitude and phase offset of the RF module., which proves the effectiveness of the method." @default.
