CsiMix-JSCC: A Lightweight Adaptive Deep Joint Source Channel Coding Framework for CSI Feedback
In frequency-division-duplexing (FDD) massive multiple-input multiple-output (mMIMO) systems, accurate downlink channel state information (CSI) feedback is essential for achieving high spectral efficiency. However, the high dimensionality of CSI leads to substantial uplink feedback overhead and makes the feedback proce...
