Analysis of Multi-User-Based UAV System With Outdated CSI

IEEE Open Journal of the Communications Society
In this paper, we investigate the performance of multiple-input and multiple-output (MIMO) unmanned air vehicle (UAV) based multi-user communication systems over generalized Nakagami- $m$ fading channels subject to channel feedback delays. The impact of

L1 Scheme for Semilinear Stochastic Subdiffusion with Integrated Fractional Gaussian Noise

Fractal and Fractional
This paper considers a numerical method for solving the stochastic semilinear subdiffusion equation which is driven by integrated fractional Gaussian noise and the Hurst parameter H∈(1/2,1).

Decay analysis of bivariate Chebyshev coefficients for functions with limited regularity

Results in Applied Mathematics
The Chebyshev polynomial approximation is a useful tool to approximate smooth and non-smooth functions. In fact, for a sufficiently smooth function, the partial sum of Chebyshev series expansion provides optimal polynomial approximation.

An Optimal Quadrature Formula Exact to the Exponential Function

Проблемы вычислительной и прикладной математики
Numerical integration of definite integrals plays a crucial role in both fundamental and applied sciences. The precision of approximate integral calculations depends on the initial data and specific conditions, which impose various requirements on the resulting computations.
