摘　　要：Sparsity modulation is a promising technology for the sixth generation(6G)of communication networks,which satisfies the high requirements in terms of spectral efficiency(SE)and energy efficiency(EE).Currently,many representative sparsity modulation schemes,such as spatial modulation,index modulation,media-based modulation,reconfigurable intelligent surface(RIS)-based/reflecting modulation,and subcarrier number modulation,have attracted the attention of the wireless research community.Different from conventional amplitude-phase modulation schemes,sparsity modulation employs one or more modulation dimension(s)in addition to the conventional amplitude-phase constellation,so as to form higher-dimensional modulation schemes,which considerably enhance the SE at a reduced implementation complexity under proper system configurations.It is worth noting that the modulation dimensions in current sparsity modulation schemes are not fully explored due to limited resources.
