Orthogonal frequency division multiplexing with index modulation (OFDM‐IM) is a promising multicarrier transmission technique that exploits both conventional modulation and the indices of active subcarriers for data transmission. In this Letter, the authors propose OFDM with power distribution index modulation (OFDM‐PIM) where a unique power distribution technique is applied to index modulated subcarriers. Furthermore, we propose OFDM with in‐phase/quadrature PIM (OFDM‐I/Q‐PIM) which performs the same power distribution process on the real and imaginary parts of the data symbols, independently. Average bit error performances of OFDM‐PIM and OFDM‐I/Q‐PIM are obtained and the superiority of the proposed schemes over reference schemes is demonstrated via extensive computer simulations.
