Study of channel state information feedback based on artificial intelligence

Study of channel state information feedback based on artificial intelligence

Accurate acquisition of CSI (channel state information) is the key to the performance of massive MIMO.In current communication systems, when the reciprocity of uplink and downlink is not ideal, codebook-based CSI feedback is used for downlink CSI acquisition.With the increase of antenna scale, codeb...
