SPP 1397: Communications in Interference Limited Networks (COIN)

无线通信网络的物理基础是电磁波在自由空间中的传播，因此对干扰现象的控制将起关键作用，干扰是无线电通信中最强的限制因素。传统通信系统中的类似方法基于蜂窝网络拓扑结构和正交接入原理，从而理想地消除了携带信息的信号之间的相互干扰。然而，传输信道的实际物理特性以及底层网络拓扑结构需要超越当前技术水平的策略和概念，特别是考虑到对最高数据速率、服务标准质量和灵活性的需求。这些新策略的目标是信息的联合（可能是分布式的）处理和编码，以及网络各节点的协作；它们产生了处理通信问题的全新方法，这些方法必须反映在全新的思维方式中。优先方案的目标是发展这些新的范例。首先，已经开始的范式变化包括不再试图以资源（能源，带宽等）为代价来避免干扰，而是系统地控制和协调它，并最终重新思考术语干扰的含义。COIN支持的第二个范式变化是基于一种替代的通信理论，它取代了传统的传输模型，并以基于证据的模型为基础：比特不是汽车！优先计划的研究目标是：(1)干扰管理和合作策略：研究和开发基于分布式算法的蜂窝和替代网络拓扑中通信过程优化的创新概念，特别是关于干扰的控制和协调以及使用分布式编码和信号处理方法的合作策略。(2)基于证据的方法：基于证据的通信技术发展的基础研究，该技术结合了分布式网络优化、网络编码和中继领域的最新方法，从而引发了通信领域范式的变革。

In wireless communication networks, of which the physical basis is the propagation of electromagnetic waves in free space, the control of interference phenomena - interference is the strongest limiting factor in radio communications - will play a key role. Comparable approaches in conventional communication systems are based on cellular network topologies and the principle of orthogonal access, thus ideally eliminating mutual interference between information carrying signals. The realistic physical properties of the transmission channel as well as the underlying network topologies, however, require strategies and concepts beyond the current state of the art, especially considering the demand for highest data rates, quality of service criteria and flexibility. The object of these novel strategies is the joint, and possibly distributed, processing and coding of information, as well as the cooperation of all nodes of the network; they result in radically novel approaches in the treatment of communications problems that must be reflected in fundamentally new mindsets. The goal of the Priority Programme is to develop these new paradigms. A first, already initiated, change of paradigm consists of no longer attempting to avoid interference at the expense of resources (energy, bandwidth etc.), but to systematically control and coordinate it, and to finally rethink the meaning of the term interference. The second change of paradigm supported by COIN is based upon an alternative theory of communications that supersedes the conventional transport model and is predicated on an evidence-based model: A bit is not a car! The research goals of the Priority Programme are: (1) Interference management and cooperative strategies: Investigation and development of innovative concepts for the optimisation of communication processes in cellular and alternative network topologies based on distributed algorithms, in particular with regard to control and coordination of interference as well as cooperative strategies using methods of distributed coding and signal processing. (2) Evidence based methods: Fundamental research for the development of evidence based communication techniques that combine the latest approaches in the areas of distributed network optimisation, network coding and relaying, and thereby initiate a change of paradigm in the area of communications.
