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.
