index modulation … and the amplitude phase modulation constellation points. This paper …

… 1 is named as the index modulation block in this paper. The p1 bits are fed to the index
selector, mapping the incoming p1 bits to a combination of K active subcarriers, ie, Ig for 0<g≤G …

… first divided into multiple layers, each determining the active subcarriers and their modulated
symbols. The index modulation (IM) bits are carried on the indices of the active subcarriers …

… index modulation (OFDM-GIM) that allows an adjustable number of active subcarriers, and
OFDM with in-phase/quadrature index modulation (OFDM-I/Q-IM) that expands the index …
