Generalized Spatial Modulation With Multi-Index Modulation
IEEE Communications Letters, 2020In this letter, we propose a novel scheme extending index dimension with two distinct signal constellations, named as generalized spatial modulation with multi-index modulation (GSM-MIM). Through this scheme, which exploits the spatial domain and index domain, more extra information bits are transmitted by the spatial indexes as compared with the ...

Novel Index Modulation Techniques: A Survey [PDF]
IEEE Communications Surveys and Tutorials, 2019 In fifth generation wireless networks, the escalating teletraffic and energy consumption has necessitated the development of green communication techniques in order to further enhance both the system’s spectral efficiency and energy efficiency. In the past few years, the novel index modulation (IM) has emerged as a promising technology that is widely ...

2020 IEEE Wireless Communications and Networking Conference (WCNC), 2020
Polar codes with short code length under successive cancellation (SC) decoding are inferior to other advanced codes of similar block length. Although more sophisticated algorithms, such as SC list (SCL) decoding and SC stack (SCS) decoding were introduced to address the problem, the complexity of these algorithms has also increased.

Filtered OFDM with Index Modulation
2018 International Conference on Advances in Computing, Communications and Informatics (ICACCI), 2018In this paper, a novel multicarrier modulation scheme called Filtered Orthogonal Frequency Division Multiplexing with Index Modulation has been proposed for operation over frequency-selective and rapidly time-varying wireless fading channels. The filtering helps restricting the Out-of-Band Emission and indexing helps in reducing Transmitter Power.

Multidimensional Index Modulation in Wireless Communications
IEEE Access, 2018 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.

Differential Subcarrier Index Modulation
IEEE Transactions on Vehicular Technology, 2018One of the main challenges in orthogonal frequency division multiplexing (OFDM)–subcarrier index modulation (SIM) systems is the huge amount of resources required to obtain channel state information at the receiver side. In this paper, a differential subcarrier index modulation (DSIM) scheme is proposed, which entirely avoids the need for any channel ...

Index Modulation Multiple Access
2018 IEEE 29th Annual International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC), 2018In this paper, the use of index modulation (IM) technique for non-orthogonal multiple access (NOMA) is presented, called the Index Modulation multiple access (IMMA). From the concept of index modulation, IMMA technique uses the active subcarriers and inactive subcarriers to make index indices.

Subcarrier-index modulation OFDM
2009 IEEE 20th International Symposium on Personal, Indoor and Mobile Radio Communications, 2009A new transmission approach, referred to as subcarrier-index modulation (SIM) is proposed to be integrated with the orthogonal frequency division multiplexing (OFDM) systems. More specifically, it relates to adding an additional dimension to the conventional two-dimensional (2-D) amplitude/phase modulation (APM) techniques, i.e. amplitude shift keying (

Index and Constellation Order Lowering for OFDM With Index Modulation
IEEE Communications Letters, 2020Orthogonal frequency division multiplexing with index modulation (OFDM-IM) is a promising variant of OFDM where indices of symbol carrying sub-carriers also convey information bits besides the complex symbols themselves. Recently, a lower order modulation variant has been proposed for OFDM-IM, where the baseband constellation is lowered with ...

Position Index Modulation for Fluid Antenna System [PDF]
IEEE Transactions on Wireless CommunicationsFluid antenna system (FAS) represents all forms of movable and non-movable position-flexible antenna system, and opens up the possibility of a new form of modulation schemes. In this paper, we investigate the design of position index modulation (PIM) for
