协同认知无线电MANET中的功率控制性能分析与仿真

针对现有移动通信系统与MANET共享同一频带时产生相互干扰的问题，文中分析了带有载干噪比信息认知方式的特征和性能，提出了基于全方位终端分布的仿真模型，并进行了计算机仿真。仿真结果证明，本方案能够较全面地反映出两个系统之间的干扰情况，分析方法和结论可以作为设计共享同一频带通信系统的参考。

Analysis and Simulation of Power Control Technology in Co-cognitive Radio and MANET

Aiming at the problem of mutual interference when existing mobile communications systems and MANET share the same frequency band, the characteristic and the performance of the cooperative cognitive mode with Carrier to-Interference and-Noise Ratio are analyzed. And the simulation model based on the omnidirectional terminal distribution is proposed. Computer simulations indicate that this scheme could more fully reflect the interference between the two systems. So the analytical method and the conclusion could serve as a reference for designing communication system sharing the same band.
