近年来，空间随机模型的基础上决定点过程（DPP）的蜂窝无线网络的分析研究作为有前途的模型。实际上，DPP可以表达在真实的蜂窝网络中观察到的宏基站（BS）配置的排斥性质，并且具有许多期望的数学性质来分析网络性能。然而，几乎所有基于DPP的模型上的先前工作都假设瑞利衰落，而基于泊松点过程的空间模型已经被开发为允许衰落/阴影传播效应的任意分布。为了使基于DPP的模型更有前途，必须将其扩展到允许非瑞利传播效应。在本文中，我们提出了下行链路蜂窝网络模型，其中的BS部署根据Ginibre点过程，这是一个主要的例子的DPPs，在Nakagami-m衰落。对于所提出的模型，我们推导出一个数值计算的覆盖概率的形式，并揭示了它的一些性质的数值和理论。
Recently, spatial stochastic models based on determinantal point processes (DPP) are studied as promising models for analysis of cellular wireless networks. Indeed, the DPPs can express the repulsive nature of the macro base station (BS) configuration observed in a real cellular network and have many desirable mathematical properties to analyze the network performance. However, almost all the prior works on the DPP based models assume the Rayleigh fading while the spatial models based on Poisson point processes have been developed to allow arbitrary distributions of fading/shadowing propagation effects. In order for the DPP based model to be more promising, it is essential to extend it to allow non-Rayleigh propagation effects. In the present paper, we propose the downlink cellular network model where the BSs are deployed according to the Ginibre point process, which is one of the main examples of the DPPs, over Nakagami-m fading. For the proposed model, we derive a numerically computable form of the coverage probability and reveal some properties of it numerically and theoretically.
