SPP 1397: Communications in Interference Limited Networks (COIN)

在无线通信网络中，其物理基础是电磁波在自由空间中的传播，对干扰现象的控制--干扰是无线电通信中最强的限制因素--将发挥关键作用。传统通信系统中的类似方法基于蜂窝网络拓扑和正交接入原理，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属性以及底层网络拓扑需要超越当前技术状态的策略和概念，特别是考虑到对最高数据速率、服务质量标准和灵活性的需求。这些新战略的目标是联合并可能分散地对信息进行处理和编码，以及网络所有节点的合作；它们在处理通信问题方面产生了全新的方法，必须从根本上反映在新的思维方式中。优先方案的目标是发展这些新的范例。第一个已经启动的范式变化包括不再试图以牺牲资源(能量、带宽等)来避免干扰，而是系统地控制和协调干扰，并最终重新思考干扰一词的含义。硬币支持的第二个范式变化是基于另一种通信理论，该理论取代了传统的交通模型，并以基于证据的模型为前提：比特不是汽车！优先方案的研究目标是：(1)干扰管理和合作战略：研究和开发创新概念，以优化基于分布式算法的蜂窝和替代网络拓扑中的通信过程，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战略。(2)基于证据的方法：为发展基于证据的通信技术而进行的基础研究，这些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的范式变化。

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.
