Embodiment Construction
[0027] An embodiment of the present invention provides a method for processing downlink array signals according to channel change information. The purpose of the method is to select whether to jointly process downlink array signals with at least two arrays or perform at least two arrays according to the actual situation of the downlink channel. independent processing of downlink array signals. In this embodiment, it is assumed that at least two antenna arrays can be calibrated jointly to offset the amplitude and phase differences of different channels. refer to image 3 , the specific execution steps are as follows:
[0028] Step 301: Estimate at least one channel state parameter.
[0029] In this embodiment, the channel state parameters include: the moving speed of the mobile terminal, channel related parameters, Doppler frequency offset of the channel, and the like. Any one or two channel state parameters can be estimated, and multiple channel state parameters can also be...
