Entropy Coding Aided Adaptive Subcarrier-Index Modulated OFDM
IEEE Access, 2018 We propose entropy coding-aided adaptive subcarrier-index-modulated orthogonal frequency division multiplexing (SIM-OFDM). In conventional SIM-OFDM, the indices of the subcarriers activated are capable of conveying extra information. We propose the novel
