Research on CSI feedback and precoding in FDD cell-free massive MIMO systems

For frequency division duplexing (FDD) cell-free massive multiple input multiple output (MIMO) systems, maximizing downlink capacity relies on designing a precoding matrix that achieves high beamforming gain and effectively suppresses multi-user interference. The accurate acquisition of downlink cha...
