OFDM APPARATUS AND METHOD FOR INDEX MAPPING BASED ON SUBCARRIER DIVISION FOR OFDM INDEX MODULATION

摘要

An index mapping method based on subcarrier division for OFDM index modulation, and the index mapping method (a) divides all subcarriers included in the OFDM subblock into a plurality of groups, and as a parameter for each group, each of the plurality of groups Determining a parameter regarding the number of subcarriers per group for each group, and a parameter regarding the number of active subcarriers per group that is activated among subcarriers per group; And (b) performing index mapping for OFDM index modulation using the determined group-specific parameters.
