摘要
认知无线电与能量的结合提高了频谱的利用效率和对绿色能源的使用。为减弱对主用户的干扰以及次用户功率分配的有峰值限制,文章首先分析了认知无线电网络的系统模型,进而阐述了动态吞吐量最大化分配算法,最后通过实验分析和验证说明了该课题的最优功率控制的独特性和完备性。
Combined with Cognitive Radio and energy to improve the efficiency of spectrum utilization and use of green energy. To attenuate interference to the primary user and a secondary user has a peak power allocation limit, this paper analyzes the model of cognitive radio network, and then describes the dynamic allocation algorithm to maximize throughput, and finally through the analysis and validation experiments illustrate the present topic optimal power control uniqueness and completeness.
