| 摘 要： | 为有效利用频谱资源，提高频谱效率，文中利用环境感知技术，设计出认知无线电跨层结构框架，提出一种新的功率控制博弈BPCG（Bandwidth and Power Control Game Algorithm）算法。研究不同用户的频谱带宽分配和功率控制，该算法在确保频谱带宽有效分配前提下，通过对用户功率的有效控制，实现网络总吞吐量的提高。仿真结果表明该算法在相同的功率消耗前提下，网络吞吐量显著提高，并随频谱带宽的增加，实现网络吞吐量的最大化。

| Abstract: | To increase the efficiency of spectrum utilization and improve system performance, we developed a cross-layer design framework which combines spectrum bandwidth allocation with power control for cognitive radios, and proposed a novel throughput game algorithm BPCG（ Bandwidth and Power Control Game Algorithm）. The simulation results show that the algorithm can increase the total throughput markedly under the same power consumption. Moreover, with the increment of spectrum bandwidth, the total throughput is maximized. |
