Discrete fourier transform spread zero word OFDM
(Institute of Electrical and Electronics Engineers Inc., 2017)
Fifth generation (5G) waveform must meet a superior performance in multipath channels along with low peak to average power ratio (PAPR), especially in up-link transmission. Among waveform candidates, zero tail (ZT) DFT-spread ...
Numerical characterization of in vivo wireless communication channels
(Institute of Electrical and Electronics Engineers Inc., 2014)
In this paper, we numerically investigated the in vivo wireless communication channel for human male torso at 915 MHz. Results show that in vivo channel is different than the classical communication channel and location ...
Controlled inter-carrier interference for physical layer security in OFDM systems
(Institute of Electrical and Electronics Engineers Inc., 2016)
Performance of OFDM is known to be very sensitive to frequency synchronization errors. By exploiting this feature, a novel technique is proposed to provide secure communication against eavesdropping. The technique is based ...
Suppressing alignment: An approach for out-of-band interference reduction in OFDM systems
(Institute of Electrical and Electronics Engineers, 2015)
In this work, we introduce a novel approach, called suppressing alignment, to reduce the out-of-band (OOB) interference of orthogonal frequency division multiplexing (OFDM) systems. Suppressing alignment exploits the ...
Mobility performance of macrocell-assisted small cells in Manhattan model
(Institute of Electrical and Electronics Engineers Inc., 2014)
Macrocell-assisted small cell concepts, such as "Phantom cell concept" and "soft cell concept", have been proposed previously for interference management, flexible cell planning, and energy saving in dense small cell ...
On reducing multiband spectrum sensing duration for cognitive radio networks
(Institute of Electrical and Electronics Engineers Inc., 2016)
In this work, the total spectrum sensing duration required for cognitive radios in multiband environments is studied to minimize the reactive handoff latency. Two spectrum sensing strategies, namely window-based and ...
Inter numerology interference analysis for 5G and beyond
(Institute of Electrical and Electronics Engineers Inc., 2018)
One of the defining characteristics of 5G is the flexibility it offers for supporting different services and communication scenarios. For this purpose, usage of multiple numerologies has been proposed by the 3rd Generation ...
Hybrid precoding for mm Wave massive MIMO systems with generalized triangular decomposition
(Institute of Electrical and Electronics Engineers Inc., 2018)
Hybrid precoding schemes have recently gained a great attention for millimeter wave (mmWave) massive multiple-input-multiple-output (massive MIMO) communication systems because of offered cost and low-power consumption ...
A flexible hybrid waveform
(Institute of Electrical and Electronics Engineers Inc., 2017)
Cellular systems of fifth generation (5G) require a waveform with flexible guard interval length along with a low power consumption. Different cyclic prefix (CP) durations in long term evolution (LTE) result in loss of ...
Communications scenarisos and a new mixed numerology set for flying base stations in 5g and beyond
(Institute of Electrical and Electronics Engineers Inc., 2018)
In many ongoing universal projects, base stations are located in the different type of aerial vehicles with the increasing number of aeronautical platforms and applications. It triggers the different research opportunities ...
