Physical effect of in-phase and quadrature imbalance in delay-doppler domain
(Institute of Electrical and Electronics Engineers Inc., 2021)
Orthogonal time frequency space (OTFS) technique is a recent two-dimensional (2-D) modulation aiming to exploit both time and frequency selectivity of doubly dispersive wireless channel, which significantly affects the ...
Performance analysis of OTFS under in-phase and quadrature imbalance at transmitter
(IEEE-Institute of Electrical and Electronics Engineers Inc., 2021)
The influence of in-phase and quadrature (IQ) imbalance on the performance of orthogonal time frequency space (OTFS) transmission is investigated in this work. OTFS is a recent two-dimensional transmission scheme with ...
A secure downlink NOMA scheme against unknown internal eavesdroppers
(IEEE-Institute of Electrical and Electronics Engineers Inc., 2021)
Enhancing security level against potential internal eavesdroppers in Non-Orthogonal Multiple Access (NOMA) has been reported as a serious challenge. In this letter, a novel secure NOMA scheme based on physical-layer security ...
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 ...
