Demands for wireless access to the Internet and voice communicationskeep growing exponentially, while the available spectrum remains scarce.As a result, cellular, WiFi, mesh, and cognitive networks areincreasingly interference-limited.Despite significant efforts over the last decade, key aspects of theinterference are still not well understood. In particular, the spatialand temporal correlation of the interference has been largely ignored,despite its profound impact on the performance. With the propermathematical and numerical tools from stochastic geometry and spatialstatistics, the impact of protocol decisions on the interference as arandom field in space and time can be assessed, and, even moreimportantly, the question of how to engineer the interference foroptimum performance can be addressed.This project aims at taking a major step in this direction. It focuseson developing a fundamental understanding of the structure of theinterference using a rigorous analytical approach. While the outcomes ofthe project will be applicable to and relevant for most modern wirelesssystems, they are particularly pertinent for cognitive systems, whereinterference between primary and secondary users is not just a technicalproblem leading to a performance reduction, but also a regulatory andlegal issue.

无线接入互联网和语音通信的需求持续呈指数级增长，而可用的频谱仍然稀缺。因此，蜂窝、WiFi、网状和认知网络的干扰越来越有限。尽管在过去十年中做出了重大努力，但干扰的关键方面仍然没有得到很好的了解。特别是，干扰的时空相关性在很大程度上被忽略了，尽管它对性能有深刻的影响。利用随机几何和空间统计学中适当的数学和数值工具，可以评估协议决策对干扰在空间和时间上的随机场的影响，更重要的是，可以解决如何设计干扰以获得最佳性能的问题。本项目旨在朝着这个方向迈出重要的一步。它的重点是用严格的分析方法对干扰的结构有一个基本的理解。虽然该项目的成果将适用于大多数现代无线系统并与之相关，但它们尤其与认知系统相关，在认知系统中，主用户和辅助用户之间的干扰不仅是导致性能下降的技术问题，也是监管和法律问题。
