Index Coded PSK Modulation [PDF]

open access: yes2016 IEEE Wireless Communications and Networking Conference, 2015
In this paper we consider noisy index coding problem over AWGN channel. We give an algorithm to map the index coded bits to appropriate sized PSK symbols such that for the given index code, in general, the receiver with large amount of side information ...

Space-Time Index Modulation [PDF]

open access: yes2017 IEEE Wireless Communications and Networking Conference (WCNC), 2016
In this paper, we present a new multi-antenna modulation scheme, termed as {\em space-time index modulation (STIM)}. In STIM, information bits are conveyed through antenna indexing in the spatial domain, slot indexing in the time domain, and $M$-ary ...

Capacity of Coded Index Modulation [PDF]

open access: yes2015 IEEE International Symposium on Information Theory (ISIT), 2015
We consider the special case of index coding over the Gaussian broadcast channel where each receiver has prior knowledge of a subset of messages at the transmitter and demands all the messages from the source.

Multidimensional Index Modulation in Wireless Communications [PDF]

open access: yes2017 Information Theory and Applications Workshop (ITA), 2017
In index modulation schemes, information bits are conveyed through indexing of transmission entities such as antennas, subcarriers, times slots, precoders, subarrays, and radio frequency (RF) mirrors.

Dual-Mode Index Modulation Aided OFDM

open access: yesIEEE Access, 2017
Index modulation has become a promising technique in the context of orthogonal frequency division multiplexing (OFDM), whereby the specific activation of the frequency domain subcarriers is used for implicitly conveying extra information, hence improving

Index and Composition Modulation [PDF]

open access: yesIEEE Communications Letters, 2021
In this paper, we propose a novel modulation concept which we call \emph{index and composition modulation (ICM)}. In the proposed concept, we use indices of active/deactive codeword elements and compositions of an integer to encode information. In this regard, we first determine the activated codeword elements, then we exploit energy levels of these ...

Hamming Distance Optimized Underwater Acoustic OTFS-IM Systems

open access: yesEntropy, 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 ...

A Novel Index Modulation Dimension Based on Filter Domain: Filter Shapes Index Modulation [PDF]

open access: yesIEEE Transactions on Communications, 2021
A novel domain for Index Modulation (IM) named “Filter Domain” is proposed. This new domain generalizes many existing modulations and IM domains. In addition, a novel scheme “Filter Shape Index Modulation” (FSIM) is proposed. This FSIM scheme allows a higher Spectral Efficiency (SE) gain than the time and frequency IM dimensions in Single-Input Single ...

System-Level Assessment of a C-RAN based on Generalized Space–Frequency Index Modulation for 5G New Radio and Beyond

open access: yesApplied Sciences, 2022
Index modulation (IM) has been attracting considerable research efforts in recent years as it is considered a promising technology that can enhance spectral and energy efficiency and help cope with the rising demand of mobile traffic in future wireless ...
