This paper studies a grant-free non-orthogonal multiple access (GF-NOMA) system using orthogonal frequency division multiplexing (OFDM) in the presence of carrier frequency offsets (CFOs). We propose pilot placement suitable for CFO estimation and structured data symbols based on low-density signature OFDM (LDS-OFDM). The receiver design exploiting side information (SI) generated from the data structure via Bayesian inference is further proposed. Numerical results demonstrate our proposed system outperforms the conventional method by properly utilizing SI. |
