A Survey and Comparison of the Performance of Several Index Modulation Optimization Schemes

In the era of the explosion of mobile data services, global communication workers aim to provide better mobile communication services and promote the development of emerging fields. Based on this, index modulation has been developed. In this paper, we provide a comprehensive survey and comparison of some of the most promising IM optimization schemes, including OFDM-IM-SL, OFDM-IM-SM, OFDM-IM-MSC, ML-Optimum Decoding and ICI Self-Cancellation technologies. The comparison is based on several evaluation metrics such as spectral efficiency, bit error rate, and energy efficiency. The findings indicate that each IM optimization scheme has its advantages and disadvantages, and the choice of a particular optimization scheme depends on specific system requirements and will be detailed talked about in this paper. Also, this paper will provide valuable insights for future research to explore the integration of multiple optimization schemes and other advanced technologies to achieve even better performance in practical applications.
