通信无线资源调度系统设计

Design of Communication Wireless Resources Scheduling System

为了达到对空间无线电资源的有效管理,提高频谱资源的利用率,在认知用户可以准确获取空间频谱利用情况和无线资源特征的前提下,提出了短时和长期学习的无线资源体统调度模型。根据认知用户对空间某点的无线信号进行特征提取,得到频谱的利用情况和各个信道的特征参数,如调制方式、带宽、中心频率和功率,根据用户的发射机特性,利用层次分析法结合测量的信道参数,给出可用信道的特征参数,以供认知用户参考。长期对某一固定点进行测量记录后根据历史数据进行复合,作为认知用户机特征参数跳变的根据,以给出合理的建议。

To manage resources of space radio and improve use ratio of spectrum resources,a wireless resources scheduling model for short-term and long-term learning is proposed in the condition of that cognitive users can accurately obtain space spectrum utilization and wireless resources characteristics.Based on feature extraction for wireless signal of some space point by cognitive users,the spectrum utilization,characteristic parameters of each channel,such as channel modulation patterns,bandwidth,center frequency and power are gained.According to the characteristics of transmitter,analytical hierarchy process（AHP） combining with channel parameters can show the characteristic parameters of available channel for cognitive users.Observing the long-term data,the characteristic parameters jumping of cognitive users is presented to avoid the interference on authorized user.
