研究了目的端存在多个独立干扰源时，放大转发两跳两用户信道的公共中断性能。首先推导了公共中断概率的精确积分表达式。然后，为了降低计算复杂度，一个封闭的形式近似的共同中断概率的推导。最后，基于近似表达式进行了渐近分析。数值结果表明，公共中断概率的积分形式，相应的近似和渐近结果与Monte Carlo模拟吻合良好。
The common outage performance of an amplify-and-forward two-hop two-user channel is studied in the presence of multiple independent interferers at the destination. First, the exact integral form expression of the common outage probability is derived. Then, in order to decrease the computation complexity, a closed-form approximation of the common outage probability is derived. Finally, the asymptotic analysis is performed based on the approximation expression. Numerical results demonstrate that the integral form of the common outage probability, the corresponding approximation and the asymptotic results match well with the Monte Carlo simulations.
