Dual-polarized wideband 5G N77 band slotted MIMO antenna system for next-generation smartphones
(Institute of Electrical and Electronics Engineers Inc., 2024)
In this work, a slotted wideband eight-element multiple-input multiple-output (MIMO) antenna system is presented, which covers the N77 (3.2-4.2 GHz) frequency band. The MIMO antennas are printed on a 0.8-mm-thick FR-4 ...
Waveform design with constellation extension for OFDM dual-functional radar-communications
(Institute of Electrical and Electronics Engineers Inc., 2023)
Orthogonal frequency division multiplexing (OFDM) is widely used and works efficiently for the communication, but emerging applications requires OFDM to be flexible to meet sensing requirements. The time-frequency waveform ...
Stability of periodic waves for the defocusing fractional cubic nonlinear Schrödinger equation
(Elsevier B.V., 2024)
In this paper, we determine the spectral instability of periodic odd waves for the defocusing fractional cubic nonlinear Schrödinger equation. Our approach is based on periodic perturbations that have the same period as ...
Exploring the prognostic significance of set-domain containing 2 (setd2) expression in advanced and castrate-resistant prostate cancer
(2024)
SET-domain containing 2 (SETD2) is a histone methyltransferase and an epigenetic modifier with oncogenic functionality. In the current study, we investigated the potential prognostic role of SETD2 in prostate cancer. A ...
A novel delay-doppler-based channel estimation method in doubly-dispersive ocdm systems
(2024)
Orthogonal chirp division multiplexing (OCDM) has recently emerged as a new candidate for the 6G waveform. In high-mobility wireless channels, the inseparability of the data symbols in both time and frequency domains makes ...
Optimal handover optimization in future mobile heterogeneous network using integrated weighted and fuzzy logic models
(2024)
High mobility travelling trains and drones connected via ultra-dense mobile networks may lead to frequent handovers (HOs). As a consequence, this could arise the mobility problems of the serving network such as handover ...
High range resolution at reduced sampling rates in OFDM systems exploiting pilot aliasing
(2024)
High range resolution (HRR) is critical for automotive radar where it is directly dependent on the available transmission bandwidth. However, HRR sensing for OFDM entails high sampling frequencies, which extends the system's ...
A novel HARQ design for RSMA networks
(2024)
Rate splitting multiple access (RSMA) has a variety of advantages, including higher throughput, enhanced capacity, and network efficiency, which makes it suitable for beyond fifth generation (5G) networks. Since the combining ...
