Cp-less ofdm with alignment signals for enhancing spectral efficiency, reducing latency, and improving phy security of 5g services
(Institute of Electrical and Electronics Engineers Inc., 2018)
Although orthogonal frequency-division multiplexing (OFDM) is a widely accepted waveform in many standards and is expected to keep its dominance in future 5G systems with various types of parameterized waveforms, its ...
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 ...
Modulation options for OFDM-based waveforms: Classification, comparison, and future directions
(IEEE-Inst Electrİcal Electronics Engineers Inc, 2019)
This paper provides a comparative study on the performance of different modulation options for orthogonal frequency division multiplexing (OFDM) in terms of their spectral efficiency, reliability, peak-to-average power ...
Flexible radio access beyond 5G: A future projection on waveform, numerology, and frame design principles
(IEEE-Inst Electrical Electronics Engineers Inc, 2017)
To address the vast variety of user requirements, applications, and channel conditions, flexibility support is strongly highlighted for 5G radio access technologies (RATs). For this purpose, usage of multiple orthogonal ...
Reliability enhancement in multi-numerology-based 5G new radio using INI-aware scheduling
(Springeropen, 2019)
Multi-numerology waveform-based 5G new radio (NR) systems offer great flexibility for different requirements of users and services. However, there is a new type of problem that is defined as inter-numerology interference ...
