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

Joint Source-Channel Decoding of Polar Codes for Language-Based Source
, 2016 We exploit the redundancy of the language-based source to help polar decoding. By judging the validity of decoded words in the decoded sequence with the help of a dictionary, the polar list decoder constantly detects erroneous paths after every few bits ...
