| 摘 要： | 研究在给定频谱池的前提下,在一定区域内,系统以集中方式动态分配相关通信节点的频谱资源。即在一定的区域内认知无线电的各个通信节点间的发射信号对主用户的干扰温度不大于主用户的接收机灵敏度的前提下,对于剩余的频谱资源采用频率、功率为主的分配方法,在特定条件下还可以利用极化域进行极化分配,和利用某些设备的波束有方向性进行空域的分配。

| Abstract: | At a certain area,spectrum assignment of cognitive wireless in central mode,based on giving spectrum pool.As a condition that jamming temperatures caused by all cognitive communication nodes are less than the receiver sensitivity of main users,Frequency and energy was adopted as main method to assign the left spectrum resource.At special condition we can also adopt space field to assign the spectrum by utilizing directional beam,and adopt polarization field to assign spectrum by utilizing intersecting polarization. |
