To develop and evaluate a decentralized Q-learning algorithm for power allocation that maximizes secondary receiver signal quality while satisfying primary user interference constraints.
Designed a distributed Q-learning framework incorporating primary network protection thresholds and tunable cost functions to promote user fairness.
Evaluated the algorithm via numerical simulations of independent secondary cells located at the border of a primary network protection contour in comparison to an optimal centralized scheme.
Demonstrated secondary network performance approaching centralized optimal power allocation benchmarks while consistently maintaining primary receiver protection constraints.
Determined the optimal execution frequency and identified exploration strategies that optimize secondary user fairness and overall system throughput.
