As a baseline, the logarithm barrier method is applied to solve the adaptive modulation problem formulated with an inequality constrained secrecy capacity maximization. However, the interested problem requires to jointly solve plural sub-problems to select the best alphabet-set, which incurs a high complexity issue for the baseline technique due to identifying infeasible cases. Hence, we propose a new cache-Aided power optimization algorithm that finds the optimal solution with a statistically independent complexity order of the number of the sub-problems. Simulation results obtained in MIMO-ME scenarios verify the effectiveness of the new cache-Aided bisection (C-bisect) method that it achieves normalized throughput performance of 0.95. |
