Precoding based cross-tier interference mitigation in centralized-RAN
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2021)
This letter considers a two-tier downlink interference problem as a case of study, where macrocell user equipment (UE) shares the same frequency band with femtocell UE and suffers from severe cross-tier interference. Power ...
User pairing and power allocation strategies for 3D VLC-NOMA systems
(Institute of Electrical and Electronics Engineers Inc., 2020)
In this letter, we propose two novel, yet efficient, user pairing schemes for non-orthogonal multiple access (NOMA) in 3D visible light communication (VLC). Our analysis is carried out assuming different heights for the ...
Numerology scheduling for PAPR reduction in mixed numerologies
(IEEE-Institute of Electrical and Electronics Engineers Inc., 2021)
The flexible mixed-numerology structure with orthogonal frequency division multiplexing (OFDM) waveform is a key enabler to meet the requirements of various applications in fifth-generation (5G) and beyond wireless networks. ...
A two-antenna single RF front-end DOA estimation system for wireless communications signals
(Institute of Electrical and Electronics Engineers, 2014)
Both adaptive beamforming methods and interference management systems improve the capacity of wireless communications systems, however they may require direction of arrival (DOA) information of signals. On the other hand, ...
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). ...
Cyclic feature suppression for physical layer security
(Elsevier Sciences Bv, 2017)
Cyclic prefix (CP) deploying techniques such as orthogonal frequency division multiplexing (OFDM) and single carrier frequency domain equalization (SC-FDE) offer considerable advantages in terms of equalizing time dispersive ...
Time-asymmetric and subcarrier-specific pulse shaping in ofdm-based waveforms
(Institute of Electrical and Electronics Engineers, 2015)
In orthogonal frequency-division multiplexing (OFDM) systems, suppressing the out-of-band (OOB) emission with pulse shaping comes with a price. The expense emerges in designing the transition between consecutive symbols. ...
Emulation techniques for small scale fading aspects by using reverberation chamber
(Ieee-Inst Electrical Electronics Engineers Inc, 2019)
Reverberation chambers (RVCs) are used to provide an efficient and reliable testbed for emulating the wireless channel effects in the laboratory environment. In the literature, various techniques have been studied to enrich ...
Theoretical analysis of the co-existence of LTE-A signals and design of an ML-SIC Receiver
(Institute of Electrical and Electronics Engineers, 2015)
The increasing number of mobile devices and the demand for large throughput requiring applications has hampered access to the limited frequency spectrum. The goal of this work is to introduce a new degree of freedom to the ...
A hybrid downlink NOMA with OFDM and OFDM-IM for beyond 5G wireless networks
(IEEE - Institute of Electrical and Electronics Engineers, Inc., 2020)
In this paper, a hybrid power domain non-orthogonal multiple accessing (NOMA) scheme by the superposition of orthogonal frequency division multiple accessing (OFDM) and index modulated OFDM (OFDM-IM) technologies is presented ...
