分布式无线通信系统的性能是由系统边界和干扰机制决定的。在本文中，我们提出了一种新的无线系统在限定域内的覆盖和连通性分析。具体地说，分析了一个接收机连接到最近的发射机的系统。使用来自随机几何的工具，我们导出了一般几何形状（包括圆形和矩形）的量化系统性能对接收器位置的依赖的一般表达式。所开发的理论和表达式提供了新的见解，说明必须在现有网络中部署额外的节点，以最大限度地提高所需的服务质量。我们进一步将分析扩展到使用最大比率传输（MRT）或联合传输（如CoMP和其他分布式天线系统）的多个协作发射机的网络。我们的研究结果表明，虽然有更多的协作发射器可以提高系统的性能，但由于域几何形状导致的伪影无法消除。我们通过模拟证实了我们的分析。
The performance of distributed wireless communication systems is dictated by the system boundaries and the interference regimes. In this paper, we present a novel coverage and connectivity analysis of a wireless system within confined domains. Specifically, a system where the receiver connects to the nearest transmitter is analyzed. Using tools from stochastic geometry, we derive general expressions quantifying the dependence of the system performance on the location of the receiver for general geometries, inclusive of circles and rectangles. The developed theory and expressions provide new insights on where additional nodes must be deployed in an existing network in order to maximize a desired quality of service. We further extend the analysis to networks with multiple collaborating transmitters which use maximum ratio transmission (MRT) or joint transmission such as in CoMP and other distributed antenna systems. Our results indicate that while having more collaborating transmitters can improve the performance of the system, artefacts due to the domain geometries cannot be eliminated. We corroborate our analysis through simulations.
