Modified Orthogonal Matching Pursuit (MOMP)-based Multiuser Detector for Uplink Grant Free NOMA Systems

International Conference on Signal Processing and Communication Systems, 2019
A multiuser detection (MUD) scheme, the modified orthogonal matching pursuit (MOMP)-based MUD is proposed for uplink grant free non-orthogonal multiple access (NOMA) systems.

Development of the second-order derivatives of the Earth’s potential in the local north-oriented reference frame in orthogonal series of modified spherical harmonics

Journal of Geodesy, 2008
The second-order derivatives of the Earth’s potential in the local north-oriented reference frame are expanded in series of modified spherical harmonics. Linear relations are derived between the spectral coefficients of these series and the spectrum of the geopotential. On the basis of these relations, recurrence procedures are developed for evaluating

New Representation of Hasimoto Surfaces with the Modified Orthogonal Frame

2021
In this study, we investigate Hasimoto surfaces considering the modified orthogonal frame. Firstly, we recall the relations between the Frenet frame and the modified orthogonal frame, and then we give the evolution equations of the modified orthogonal frame. After that, the first and second fundamental forms, mean curvatures, and Gaussian curvatures of

On the modified orthogonal frames of the non-unit speed curves in Euclidean Space E3

2022
In this study, the modified frames with both the non-zero curvature and the torsion of the non-unit speed curves in Euclidean space E3 are examined. The relationships between the derivative vectors of the modified frames and the Frenet vectors or the vectors of the modified frames of the curve are given.

Orthogonal Delay-Doppler Division Multiplexing with FMCW for ISAC

ICC 2025 - IEEE International Conference on Communications
Orthogonal delay-Doppler (DD) division multiplexing (ODDM) modulation has recently been proposed as a promising paradigm for communications in doubly-selective channels. In this work, we propose a novel ODDM with frequency modulated continuous wave (FMCW)
