Abstract

The invention discloses a multi-antenna correction method, a multi-antenna transmitter and a base station system, wherein the device includes at least one antenna, at least a duplex module, at least a stimulated emission channel and a digital emission channel, at least a stimulated receiving channel and a digital receiving channel, a DPD feedback channel, and a multi-antenna correction channel, wherein, the DPD feedback channel is used for receiving the operation signals output by the stimulated emission channel, and transmitting to the PD coefficient computing module to compute the obtained PD coefficient, and outputting to the digital emission channel to perform DPD correction; the multi-antenna correction channel computes the Tx correction coefficient according to the Tx correction signal and transmits to the digital emission channel to transmit the correction, or obtains the Rx correction coefficient according to the Rx correction signal, transmits to the digital receiving channel for receiving correction. According to the invention, the multi-antenna correction and DPD correction are combined, thereby advancing system performance.

Description

technical field [0001] The invention relates to the field of electronic communication, in particular to a multi-antenna correction method, a multi-antenna transceiver device and a base station system. Background technique [0002] Multi-antenna transceiver devices, especially the Adaptive Antenna System (AAS), also known as the Smart Antenna System (SAS), the principle of the smart antenna is to direct the radio signal to a specific direction to generate a spatially directional beam. Align the main beam of the antenna with the Direction of Arrival (DOA) of the user signal, and align the side lobe or null trap with the direction of arrival of the interference signal, so as to fully and efficiently use the mobile user signal and delete or suppress the interference signal. At the same time, smart antenna technology utilizes the difference in signal space characteristics between mobile users to receive and transmit multiple mobile user signals on the same channel through array a...
