Subblock Aided OFDM with Index Modulation

Öz

Recently, orthogonal frequency-division multiplexing (OFDM) with index modulation (IM) has been appeared as a novel method for future wireless communication systems. However, such a mechanism has low spectral efficiency due to some sub-carriers are not activated in order to implicitly convey information. In this paper, a subblock dependent approach, called sub-block aided OFDM-IM (SA-OFDM-IM) technique, is proposed for spectral efficiency enhancement of the OFDM-IM scheme with low complexity. The simulation results illustrate that the proposed SA-OFDM-IM and well known OFDM-IM have the same bit error rate (BER) performance while SA-OFDMIM has40% more spectral efficiency with low complexity
