| 研究了认知无线电Ad Hoc网络的单跳传输能力，该网络与主用户网络工作在同一地理区
域和共享同一频谱。主用户网络具有更高的优先级访问认知用户网络频谱，认知网络需要控
制其发射机密度以限制对主用户干扰。认知、主用户节点位置假设服从泊松点分布，推导了
认知、主用户网络单跳传输容量,最后进行了仿真验证其正确性。仿真结果表明：主用户网
络传输容量随主用户中断概率增加而增加，随增量中断概率的增加而降低。认知用户网络传
输容量仅由次用户中断概率参数决定。 |

| Abstract: |
| This paper analyzes the transmission capacities of cognitive Ad Hoc network wit
h single hop that operates in the same geographic region and shares the same spe
ctrum with a primary(PR) network. The PR network has a higher priority to access
the spectrum without particular considerations for the secondary(SR) network, w
here the SR network limits its interference to the PR network by carefully contr
olling the density of its transmitters. Assuming that the nodes are distributed
according to Poisson point processes,their normalized transmission c
apacities are studied and the validity is verified by simulations. Simulation re
sults indicate that the transmission capacity of PR network increases as the outage pr
obability of the PR network and decreases as increment of the outage probability
of it. The transmission capacity of SR network only do something with the outage
probability of the SR network. |
