RIS Grouping Based Index Modulation for 6G Telecommunications
IEEE Wireless Communications Letters, 2022In this letter, a novel reconfigurable intelligent surface (RIS) grouping based index modulation (RGB-IM) is proposed to enhance spectral efficiency and improve bit error rate (BER). The idea is to divide an RIS into several number of group-surfaces (GR).

Performance of LoRa-Based Schemes and Quadrature Chirp Index Modulation
IEEE Internet of Things Journal, 2022This article proposes new approximations for the bit error probability of several LoRa-based schemes, such as phase-shift keying (PSK) LoRa, in-phase and quadrature (IQ) chirp spread spectrum (CSS), discrete chirp rate keying (DCRK) CSS, and CSS with ...

On the Capacity of Index Modulation
IEEE Transactions on Wireless Communications, 2022Index modulation represents the transmitted information in two parts: by selecting a subset of available transmission dimensions (antennas, sub-carriers, or time-slots) whose selection index carries information, and by modulation symbols transmitted in ...

Sequency Index Modulation: A Novel Index Modulation for Delay-Sequency Domain Waveforms
IEEE Wireless Communications Letters, 2023In this letter, the sequency domain is introduced as a novel resource to propose a new index modulation, which is named sequency index modulation (SeIM). In SeIM, information bits are implicitly conveyed through the indices of the activated sequencies enabling bit error rate (BER), spectral efficiency, and power efficiency enhancement.

Deep Learning-Based Detector for Dual Mode OFDM With Index Modulation
IEEE Wireless Communications Letters, 2021In this letter, we propose a deep learning-based dual mode orthogonal frequency division multiplexing with index modulation (DM-OFDM-IM) detector called DeepDM, which is close to optimal bit error rate (BER) performance with low computational complexity.

Journal of the Optical Society of America A, 1990
We present a brief tutorial overview of the basic physics of periodically modulated index structures and how they affect an incident electromagnetic wave in various simple limits. Discussions of the wave-vector spectrum, coupled-amplitude equations, and finite grating-size effects are included.
