中文摘要：
采用随机几何方法对认知共存网络中认知用户对主用户造成的累加干扰进行建模，并在无衰落信道和瑞利衰落信道中分别分析了主用户采用放大重传协作通信模式下的中断概率和传输容量。仿真结果表明，放大重传模式可以有效降低共存网络中主用户的中断概率、提高主用户的传输容量。且易于实现。
英文摘要：
A stochastic geometry method was proposed to model aggregate interference in cognitive coexistent network where primary（PR） network and secondary （SR） network coexist together. Outage probability and transmission capacity for cooperation transmission of Amplify-and-Forward （AF） schemes were analyzed in channels without fading and Rayleigh fading channels based on the aggregate interference model. Simulation results showed that AF scheme can effectively reduce the outage probability and increase the transmission capacity of the primary user in a cognitive coexistent network and easy to implement.
