Experimental demonstration of optical OFDM with subcarrier index modulation for IM/DD VLC [PDF]

, 2019
We for the first time experimentally demonstrate an IM/DD VLC system using optical OFDM with subcarrier index modulation (OFDM-SIM) and digital pre-equalization. Experimental results show that OFDM-SIM achieves greatly improved BER performance than classical OFDM.

Movable-Antenna Index Modulation (MA-IM): System Framework and Performance Analysis [PDF]

This paper proposes a movable-antenna-based index modulation (MA-IM) framework that exploits the spatial mobility of a single reconfigurable antenna to create additional information-bearing dimensions for next-generation wireless systems. By discretizing the continuous movable region into a dense set of candidate sampling points and selecting ...

Hamming Distance Optimized Underwater Acoustic OTFS-IM Systems

Entropy, 2023
The orthogonal time frequency space (OTFS) modulation technique can provide reliable communication in time-varying channels. Due to the dispersive characteristics of underwater acoustic channels, this paper proposes an OTFS-IM underwater acoustic ...

Discrete Multitone Modulation for Maximizing Transmission Rate in Step-Index Plastic Optical Fibres [PDF]

, 2009
The use of standard 1-mm core-diameter step-index plastic optical fiber (SI-POF) has so far been mainly limited to distances of up to 100 m and bit-rates in the order of 100 Mbit/s.

Subcarrier Grouping-Enabled Improvement in Transmission Performance of Subcarrier Index-Power Modulated Optical OFDM for IM/DD PON Systems [PDF]

Journal of Lightwave Technology, 2018
As an improved variant of a previously published subcarrier index-power modulated optical orthogonal frequency division multiplexing (SIPM-OOFDM), a signal transmission technique termed SIPM-OOFDM with subcarrier grouping (SIPM-SG-OOFDM) is proposed and investigated for the first time.

OFDM With Hybrid Number and Index Modulation

IEEE Access, 2020
A novel transmission scheme is introduced for efficient data transmission by conveying additional information bits through jointly changing the index and number of active subcarriers within each orthogonal frequency division multiplexing (OFDM) subblock.

Vector OFDM With Index Modulation

IEEE Access, 2017
The concept of index modulation (IM) has gained increased attention in recent years. As a member of the IM family, orthogonal frequency division multiplexing with index modulation (OFDM-IM), which is able to convey additional information bits using the ...
