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 ...
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 ...
