In this work, we formulate a proportional fair resource allocation problem based on chance-constrained programming for slow adaptive OFDMA system which maximizes the average sum-rate in an adaptive time window and guarantees the Jain fair index (JFI) requirement with the target probability.
We restrict the timestep sizes used in the adaptive time integration so that they are not greater than one millisecond, that is, Δ t(max) = 1 msec.
In addition, an adaptive time stepping procedure is employed to further demonstrate efficient implementation for multi-degree of freedom, linear and nonlinear dynamical systems.
This will be area for future research as noted in the sub-section " Adaptive Time Stepping of the Controller" in the " Discussion and Conclusions" section.
In addition, the role of employing adaptive time steps in reducing the number of iterations needed for convergence is also evaluated.
The modified Euler method was used to discretise in time and an adaptive time step strategy was employed to ensure stability.
They are also robust when used in conjunction with an adaptive time stepping strategy and appear as an interesting alternative to time-splitting pseudo-spectral (TSSP) schemes.
Based on the time switching receiver architecture, the authors in [6] proposed adaptive time switching protocols for RF energy harvesting and information transmission for both AF and DF networks.
In ATDNN, adaptive time-delay units are used to capture the temporal relationships between events.
We show that adaptive time stepping in particle accelerator simulation is an enhancement for certain problems.
