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 has </span> <span class="fontstyle2">40% </span> <span class="fontstyle0">more spectral efficiency with low complexity </span>   <br style="line-height:normal;" />}, number={2}, publisher={MUSA YILMAZ}
