本文研究了发射机服从泊松点过程分布的网络中等增益接收机的成功接收概率和面积谱效率。考虑空间相关干扰信号，我们推导出两个接收天线的成功接收概率的精确解析表达式和两个以上的接收天线的紧密近似。此外，我们给出了一个近似的最佳发射机密度最大化的ASE。结果表明，完全相关的情况下，不同天线上的干扰来自同一组发射机给出悲观的成功接收概率，而不相关的情况下是乐观的。
We study the successful reception probability and the area spectral efficiency (ASE) of equal gain receivers in a network where transmitters are distributed according to a Poisson point process. Considering spatially correlated interference signals, we derive exact analytical expression of the successful reception probability for two receive antennas and tight approximations for more than two receive antennas. Also, we give an approximation for the optimal transmitter density maximizing the ASE. The results show that the fully-correlated case where interference on different antennas are from the same set of transmitters gives pessimistic successful reception probability, while the uncorrelated case is optimistic.
