Rate-Distortion-Function-Inspired CSI Feedback for FDD Massive MIMO-OFDM Communications

In this paper, we investigate the downlink channel state information (CSI) feedback for frequency-division duplexing (FDD) massive multiple-input multiple-output (MIMO) communications with orthogonal frequency division multiplexing (OFDM) modulation. By formulating CSI feedback as a lossy compression problem, we study...

ODMA-Based MIMO Massive Unsourced Random Access With Soft-Output Polar Codes

This paper investigates the design of the on-off division multiple access (ODMA) transmission scheme for multiple-input multiple-output (MIMO) massive unsourced random access (URA) systems with soft-output (SO) polar codes. First, a three-segment pilot-uncoupled coding scheme is introduced under the ODMA framework, whi...
