Self-attention mechanism-based CSI eigenvector feedback for massive MIMO

Self-attention mechanism-based CSI eigenvector feedback for massive MIMO

Massive multiple-input multiple-output (MIMO) system can provide satisfying gain of spectrum efficiency for 5G and future wireless communication systems.In frequency-division duplex (FDD) mode, downlink channel state information (CSI) needs to be accurately fed back to the base station side to obtai...
