Error performance enhancement and complexity reduction in OFDM systems via coordinate interleaving under practical impairments
(Turkiye Klinikleri, 2024)
In this work, subcarrier coordinate interleaving (CI) is implemented to orthogonal frequency division multiplexing (OFDM) systems with the aim of both enhancing the error performance and reducing the implementation complexity. ...
Orthogonal time frequency space multiple access using index modulation
(Institute of Electrical and Electronics Engineers Inc., 2023)
Orthogonal time frequency space (OTFS) is a recent two-dimensional modulation technique utilizing delay-Doppler domain and nominated as a promising candidate waveform for beyond 5G communication systems. By leveraging both ...
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 ...
Fuzzy standardized precipitation index (FSPI) for drought early warning procedure
(Springer, 2024)
There are several standardized meteorological, hydrological, agricultural, and environmental indices for drought classification into a set of dry categories all of which are derived from the basic concept of standardized ...
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 ...
Hydrothermal performance of mini-channel heat sink using nanofluids/hybrid nanofluids: a numerical study
(2024)
We investigated hydrothermal performance of the mini-channel heat sink by using water, and nanofluids/hybrid nanofluids at 1% of volumetric concentration. The water-based nanofluids studied in this work were CuO, TiO2 and ...
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 ...
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 ...
