Performance analysis of a low-complexity detection for OFDM Index Modulation over Nakagami-m fading

The performance of a low-complexity detection technique for OFDM-IM over the Nakagami-m fading channel has been analyzed. The orthogonal frequency-division multiplexing with index modulation (OFDM-IM) has recently been used in conjunction with the subcarriers using on-off keying modulation. The result shows improved performance in comparison with the conventional OFDM. The closed-form expression for the average pairwise error probability (PEP) over the Nakagami-m fading channel is derived.
