CNN-based Analog CSI Feedback in FDD MIMO-OFDM Systems

23 Oct 2019Mahdi Boloursaz MashhadiQianqian YangDeniz Gunduz

Massive multiple-input multiple-output (MIMO) systems require downlink channel state information (CSI) at the base station (BS) to better utilize the available spatial diversity and multiplexing gains. However, in a frequency division duplex (FDD) massive MIMO system, CSI feedback overhead degrades the overall spectral efficiency... (read more)
