RISUsing cubic B-spline interpolation for efficient ray-tracing-based ultrawideband propagation modeling
parameters where the number of receiving locations is large. In this paper, the computational complexity of ray tracing in ultrawideband propagation modeling is reduced by using cubic B-spline interpolation. The frequency response of the channel at each...
Efficient ultrawideband propagation modelling by using the cubic B-spline function in ray tracing calculations
and antenna patterns. This is computationally intensive especially in calculating the coverage map or finding the statistics of the channel parameters where field calculations need to be carried out at a lot of receiver locations. In this study, the cubic B-spline...
Cubic B-spline collocation method for a class of partial integro-differential equation
In this paper, a numerical method is proposed to estimate the solution of initial boundary value problems for a class of partial integro-differential equations. This is based on the cubic B-splines method for spatial derivatives while the backward...
