摘要/Abstract

摘要：

首先分析了无线区域网中无线麦克风与认知用户之间的共存问题，建立了新的无线麦克风与认知用户之间的共存模型．在此基础上，将无线区域网中多小区上行链路的信道和功率联合分配建模为势博弈，建立了每个认知用户的效用函数和系统的效用函数，并给出了数学证明．算法在执行过程中，各认知用户依据最优反应原则更新自己的策略．相比暴力搜索算法，该算法的复杂度很低．仿真结果验证了该算法的收敛性和正确性．

Abstract:

A new WM-CPE coexistence model is established based on the analysis of the interference between consumer premise equipments (CPEs) and wireless microphones (WMs) in the Wireless Regional Area Network (WRAN). The proposed joint channel and power allocation game for the uplink in multi-cells of the WRAN can be formulated as a potential game and it is guaranteed to converge to a Nash equilibrium when the best response strategy is performed after observing the opponent's response. The user's utility function and the system's potential function are given and proved. The proposed algorithm has lower complexity than the brute-force (BF) search. Simulation results verify the convergence and correctness.

Key words: wireless regional area network, cognitive radio, game theory, channel allocation, power allocation
