| 摘 要： | 使用干扰预测方程预测频域冲突时无线电设备间的电磁互扰,以寻求满足主用户网络和认知无线电网络间的电磁兼容所需的空域和能量域条件,综合考虑距离、大气损耗、可视距离等因素对设备间的互扰强度和工作效果的影响。从仿真的结果看,一般情况下两系统间超过十几千米,就会因功率或视距的原因使主用户和认知用户两个网络之间实现能量或视距的隔离,达到电磁兼容。 |
| 关 键 词： | 认知无线电 主用户 干扰预测 电磁兼容 |

| Abstract: | Forecast the interference among wireless equipments by using interference forecasting equations when they work in same frequency, in order to find the EMC condition in airspace or energy fields in which the main user net and the cognitive wireless net can work together. The paper considers the loss by distance, atmosphere and orthoptic distance etc. affecting to mutual jamming and work condition. From simulation, at the condition that the distance is longer then ten kilometers morn, that main user and cognitive wireless net can work EMC, because of energy or orthoptic distance. |
| Keywords: | cognitive wireless main user interference forecast EMC |
