对蜂窝移动的通信系统的网络性能进行评估是一个巨大的挑战。在本文中，我们提出了新的空间频谱和能量效率模型的Poisson-Voronoi镶嵌（PVT）随机蜂窝网络。针对PVT随机蜂窝网络，提出了一种基于马尔可夫链的无线信道接入模型。在此基础上，推导了PVT随机蜂窝网络的中断概率和阻塞概率，并进行了数值计算。在此基础上，综合考虑随机蜂窝网络中的呼叫到达率、路径损耗指数和基站密度，提出了PVT随机蜂窝网络的空间频谱和能量效率模型，并进行了分析。通过数值模拟，对PVT随机蜂窝网络的频谱和能量效率进行了评估。
It is a great challenge to evaluate the network performance of cellular mobile communication systems. In this paper, we propose new spatial spectrum and energy efficiency models for Poisson-Voronoi tessellation (PVT) random cellular networks. To evaluate the user access to the network, a Markov chain based wireless channel access model is first proposed for PVT random cellular networks. On that basis, the outage probability and blocking probability of PVT random cellular networks are derived, which can be computed numerically. Furthermore, taking into account the call arrival rate, the path loss exponent and the base station (BS) density in random cellular networks, spatial spectrum and energy efficiency models are proposed and analyzed for PVT random cellular networks. Numerical simulations are conducted to evaluate the network spectrum and energy efficiency in PVT random cellular networks.
