20250175378. Coding Meth (Guangdong University of Technology)
CODING METHOD AND DEVICE BASED ON MULTIPLE-MODE ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING WITH INDEX MODULATION (MM-OFDM-IM)
Abstract: a coding method based on multiple-mode orthogonal frequency division multiplexing with index modulation (mm-ofdm-im) is provided. a coded bit sequence is divided into an index-layer sequence and a symbol-layer sequence. according to the index-layer sequence and the symbol-layer sequence, a plurality of constellation modes respectively corresponding to the plurality of subcarriers and which one of a plurality of constellation symbols respectively corresponding to the plurality of constellation modes is carried by each of the plurality of subcarriers are determined. a constellation mode permutation corresponding to each of the plurality of subcarriers is in a symmetrical distribution. the coded bit sequence is converted into the plurality of constellation symbols. the plurality of constellation symbols are respectively loaded to the plurality of subcarriers. a coding device based on mm-ofdm-im is also provided.
