Abstract
This letter introduces a novel coalitional game-theoretic power allocation (CGTPA) paradigm, tailored for resource management for communication and netted radar systems. Taking the power allocation for enhancing downlink throughput in a distributed antenna system (DAS) as a clear-cut example, theoretical expositions, and experimental simulations are presented accordingly. As an optimal decision-making method grounded in behavioral rules, the CGTPA method distinguishes itself from the methods yielded by conventional convex optimization and heuristic methods. It evolves around the idea that cooperation among antennas can be modeled as a coalitional game. Then the Sharpley value-based power allocation ensures a Pareto solution for both optimality and fairness. Furthermore, it is mathematically proven that the throughput consistently improves through iterative application of the allocation rule. Mathematical analysis and simulation results validate the effectiveness of the proposed method.
期刊介绍:
The IEEE Signal Processing Letters is a monthly, archival publication designed to provide rapid dissemination of original, cutting-edge ideas and timely, significant contributions in signal, image, speech, language and audio processing. Papers published in the Letters can be presented within one year of their appearance in signal processing conferences such as ICASSP, GlobalSIP and ICIP, and also in several workshop organized by the Signal Processing Society.
