Joint Source-Channel Coding with Learnable Codebook Quantization for CSI Feedback
In this paper, we propose a joint source-channel coding (JSCC) framework with a learnable codebook quantizer (LCQ), termed JSCC-LCQ, for channel state information (CSI) feedback in frequency division duplex orthogonal frequency division multiplexing (FDD-OFDM) systems. Different from conventional codeword lookup or ind...
