Intelligent Reflecting Surface Assisted Beam Index-Modulation for Millimeter Wave Communication
TL;DR: In this article, the authors proposed three different architectures based on RISs for beam-index modulation in millimeter wave communication, which are capable of eliminating the detrimental line-of-sight blockage of millimeter-wave frequencies.

Intelligent Reflecting Surface Assisted Beam Index-Modulation for Millimeter Wave Communication
TL;DR: This work proposed to use a twin-IRS structure to construct a low-cost beam-index modulation scheme, which is capable of eliminating the detrimental line-of-sight blockage of millimeter wave frequencies.

An Optimized SLM for PAPR Reduction in Non-coherent OFDM-IM
Sarath Gopi,Sheetal Kalyani +1 more
TL;DR: In this article, a peak-to-average power ratio (PAPR) efficient non-coherent orthogonal frequency division multiplexing with index modulation (OFDM-IM) was proposed.
Journal ArticleDOI
An Optimized SLM for PAPR Reduction in Non-Coherent OFDM-IM
Sarath Gopi,Sheetal Kalyani +1 more
TL;DR: It is shown that the non-coherent OFDM-IM design, which minimizes PAPR, is a non-linear optimization problem, and a computationally efficient heuristic scheme is developed to obtain a suboptimal solution of the integer optimization problem.
Journal ArticleDOI
Coherent and non-coherent multilayer index modulation
TL;DR: A novel multilayer framework for coherent OFDM-IM is proposed, where the structure provides an improved BER performance compared to its single layer counterpart, albeit this is achieved at the cost of reduced energy efficiency.
