Low complexity peak-to-average power ratio reduction in OFDM-IM
(Institute of Electrical and Electronics Engineers Inc., 2018)
Orthogonal frequency division multiplexing with index modulation (OFDM-IM) employs the indices of the active subcarriers for information transmission, as an alternative to conventional OFDM. It offers high spectral efficiency ...
Index modulation-based flexible waveform design
(Institution of Engineering and Technology, 2020)
The service limitations of conventional orthogonal frequency division multiplexing (OFDM)-based technologies have motivated academia and industry to seek for new solutions in order to support the emerging services and use ...
Index modulation-aided IQ imbalance compensator for OTFS communications systems
(Institute of Electrical and Electronics Engineers Inc., 2022)
Design of simple transceiver architectures is inevitable in order to provide low computational complexity, low power consumption and affordable cost in beyond 5G (B5G) wireless systems, but it results in hardware impairments ...
Foreword
(Institution of Engineering and Technology, 2020)
The most critical difference of the fifth generation (5G) mobile communication technology compared to previous generations is its ability to support a wide variety of services. In other words, the 5G technology is all about ...
Multidimensional index modulation for 5G and beyond wireless networks
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2021)
Index modulation (IM) provides a novel way for the transmission of additional data bits via the indices of the available transmit entities compared with classical communication schemes. This study examines the flexible ...
OFDM-subcarrier index selection for enhancing security and reliability of 5G URLLC services
(IEEE-Inst Electrical Electronics Engineering Inc., 2017)
An efficient physical layer security technique, referred to as OFDM with subcarrier index selection (OFDM-SIS), is proposed for safeguarding the transmission of OFDM-based waveforms against eavesdropping in 5G and beyond ...
Fading-aligned OFDM with index modulation for mMTC services
(Elsevier B.V., 2019)
5th generation (5G) of wireless networking is coming with diverse use cases, such as enhanced-Mobile BroadBand (eMBB), Ultra Reliable and Low Latency Communications (URLLC), and massive Machine Type Communications (mMTC). ...
Guard band reduction for 5G and beyond multiple numerologies
(IEEE, 2020)
The existence of inter-numerology interference (INI) is a major drawback for the flexible multi-numerology frame structure proposed for the upcoming fifth generation New Radio (5G-NR). Insertion of a guard band (GB) between ...
Inter-numerology interference in OFDM-IM systems
(Wiley, 2021)
In 5G and beyond communication systems, distinct numerologies can coexist to serve diverse requirements for users and applications. However, the inter-numerology interference (INI) is a main challenge that significantly ...
Sequency index modulation: A novel index modulation for delay-sequency domain waveforms
(Institute of Electrical and Electronics Engineers Inc., 2023)
In 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 ...
